Hi Delivery Draven,
I took the liberty of spectating the game you just played (Nasus top against Malphite). I clicked the record button on OP.GG website so hopefully you'll be able to rewatch your game and follow along with my notes. Please accept my criticism positively.
00:00: First off, you are playing Nasus vs Malphite top lane. Pretty slow and dull early game lane if you ask me. Just get those Q stacks going.
2:30: Good trading, and you let the wave push your way. Nice. I'm no Nasus expert but hitting Malphite with Q's seems like a waste of mana this early.
5:50: You lost a few trades on Malphite, and he hardly lost any health. Just try to get those Q stacks up.
6:00: Good job on teammate Rengar covering the top turret while you recall.
7:20: Survived your first gank. Playing safe, I like it. Killing Malphite now that he hit level 6 is near impossible, no need to be aggro.
11:00: Rengar ganks top lane, but you are low health and mana. Malphite could probably kill you if you engaged. Good idea not following up, but perhaps let Rengar know that it's probably a lost cause ganking top lane. His time might be better spent ganking mid lane at this point (especially since Azir just burned Xerath's flash a minute or so ago). If you don't think a gank will be successful, then ping them off.
12:00: Azir is providing a ton of pressure to mid lane. As a top lane Nasus who is just focused on farming, you might be able to keep an eye out on the mini-map to make sure he's not getting ganked. Also drop a friendly reminder to Azir and Rengar to get some wards out around mid lane.
12:50: Malphite TP's bot lane to assist in a big fight. Throw down some warning pings to let them know he's tp'ing! It doesn't help much since your bot lane was already overextended, But what you do know is that you do NOT have TP. Let your teammates know you TP'd top lane a minute ago, and can't follow up when Malphite TP's. Since you are Nasus, this is a special occasion where TP'ing into an early game fight might actually be a bad decision. What you could have done here (if you had teleport off cd) was teleport to bot lane turret to save it from going down after the fight. Shoving top is probably what I would have done too.
13:03: You ward top lane River bush. This is a mistake. Malphite Just TP'd bot lane for a fight, you KNOW both enemy bot laners just died, and you see enemy Mundo bot lane as well. Xerath is still visibly shoving in mid lane, so there is no one even close to you at this point. You know the absolute soonest time someone can be toplane is in about 20-30 seconds (the time it takes Xerath to walk top lane). This ward could have been saved for 20 more seconds at least!
13:40: You are now pushed up in lane, trying to take enemy tower, without ANYONE visible on your map. You no longer have a useful ward. If you had a ward, now would be a better time to ward tri-bush. Rengar also pings top tower and is heading your way. So you know you have backup. But the enemy team could have more backup because you don't know where anyone is. A ward in tri-bush would have spotted Nautilus around 14:13 and would have saved Rengar's life. It would have also spotted Vayne coming around 14:25, which would have saved your flash.
14:30: Support Morgana making plays mid lane! Dunno why she is alone mid, but good on her for doing something productive. Good job on teammate Kalista for shoving bot lane as well.
14:50: You decide to stay at your tower and protect it from Vayne. You have no mana and no flash. Vayne could whittle you down and take your tower she wants. Enemy team decides to chase for a kill instead, but keep in mind that staying at your tower could have ended much worse. You could have recalled and gone bot lane to Q stack, or just heal up and avoid the gank.
16:30: I wouldn't recommend first building Luden's Echo like your support Morgana did, but she's doing a lot for your team right now (except placing wards). You just bought a ward, which is good. But there are no wards at all on the map right now. Sure now you could blame your teammates for not warding and getting caught out, but you could also remind everyone to buy wards on their next base.
18:30: Your team has all 3 lanes pushing right now, but NOT A SINGLE WARD IN THE ENEMY JUNGLE! Kalista was therefore overextended. You could have pinged him to back off from bot tier 2 tower. Instead he dies and you decide to solo push mid tier 2 tower. Good job applying pressure, but now you're the overextended one. Perhaps take this time to place your ward in the enemy jungle (red side is probably safer since you see Malphite and Xerath killing Kalista bot lane), then go get all the farm that's stacking up in the top lane. This is safer and also productive.
19:00: You are fortunate to survive Vayne, Mundo, and Xerath rushing you, but you left the enemy's jungle without ever placing your ward! You're now once again stuck on your side of the map with the enemy side completely in darkness.
20:55: You TP to mid lane tier 2 turret for reasons I cannot see. You spend the next 30-45 seconds chasing the enemies into their jungle (which you STILL don't have vision of) and end up getting nothing. You kill support Nautilus around 22:15 because he walked a dumb path, but this really wasn't worth the effort.
23:00: You once again walk blindly into the enemy jungle, and this time even your team is pinging you off. Dragon just spawned, you still never used your ward that you bought 5-7 minutes ago, and you just wasted your teleport and died for no reason. Instead a better play would have been to save teleport, walk top lane to apply pressure there, then teleport down to dragon when it spawns. In the meantime, you could get some wards in the enemy's top side jungle and also tell your team to group and get wards on bot side to prepare for the dragon fight. If you get ganked, your team will outnumber their team at dragon. If you don't get ganked, you get a top tower for free. Win-Win.
25:45: Your teammates are pushed up dangerously and about to fight, and you are way back getting blue buff by yourself. First, this blue buff would be better on Azir. Second, a teleport could have saved a few teammate lives. Or simply ping them back because they are overextended without any wards.
27:00: You built sunfire cape?! Sure that might be a decent item against Dr. Mundo, Nautilus, and Malphite. But I probably would have built Frozen Heart here. Vayne is a huge threat to your team, and Frozen Heart is the best item to buy against Vayne. Don't blindly accept my advice on this decision, though. But if I were one of your teammates I would very much appreciate you building a Frozen Heart against Vayne.
27:30: Have I mentioned yet that your team has no wards in the enemy jungle?!
27:50: Kalista continues to split push bot lane, but the rest of your team is trying to fight 3v5 mid lane. Politely ask Kalista to group while you split push. Or if you guys go for a 1-3-1 push, tell the 3 teammates in mid lane to back off because there's no one on the map.
29:00: You are farming top lane while the enemy is taking your mid inhibitor turret. They even engage in a fight you could have teleported to. Just some options.
30:10: You ward top river bush again. At least this time you upgraded your trinket, but that ward is useless because in 10 seconds you will already be pushed up to enemy's 2nd tier top turret. Deeper wards would have been better here, but do NOT go too far into the enemy jungle without help. Trying to get deep wards alone is the same thing as walking into a blind jungle alone. You could have safely warded a bush around enemy Red Buff though. Or at least ward baron.
30:30: Your team loses a fight that you could have teleported to. Your team loses dragon because of this. You could have instead taken this opportunity to get some deep wards in the top side jungle, because you know the enemy team is mostly at dragon. Instead you go to steal another blue buff that could have gone to Azir. League of Legends is all about trading objectives, and you missed your opportunity to do this here.
32:20: Support morgana making the plays once again! But she still doesn't have a sightstone. If she refuses to build one, then I'd suggest you or Rengar getting one (Rengar is building full damage, however). Or just ask everyone to upgrade trinkets.
33:30: Finally Kalista leaves bot lane, and you take over bot lane. Good decision. Let's talk about this teamfight though. You had good eyes up until about 34:03, where you decide to leave Kalista's side and let him try to 1v1 Xerath. You did do so in order to save Morgana though, so this is debatable. I won't say your decisions were too bad here. Morgana is performing well, and built full damage, but Kalista can get objectives.
36:00: HEYYYYY finally your team got a couple wards in the enemy jungle. That allowed you guys to safely get baron. See how effective just a couple wards in the enemy jungle can be?
37:50: You stay too long after taking an inhibitor, and this just costed you the game. The enemy can punish you by chasing you out of their base and taking a free dragon while you guys are low HP. And they do just that. You could have warded dragon, but you did ward their blue buff on your way out, so nice job with that. Your team really fails in trying to fight in your red buff jungle. You included. First, Azir goes IN without any vision of who's just outside of vision. You should have already been pinging to back off, but instead you're going in for the fight with him. You KNOW they just got dragon so you know you guys are most likely outnumbered (Rengar is in base). You also steal Red buff which could have been more useful on Rengar or Kalista. On top of this, that was Dragon #5 for the enemy team.
40:30: Your team overextends in mid without wards. Ping them off and shove side lanes!
42:00: Game over. Your team was SO close to winning. You played well, but just a couple small decisions and vision control would have won the game for your team.
