How your attitude can win you more games (LONG)
Situation
Your Irelia top lane dies for the second time in lane at the 5 minute mark. So you very kindly suggest to her: "stop feeding so I can carry". Good advice.
2 minutes later
An ally has been slain
Your Irelia is now 0/3/0 and their Darius is 3/0/0 at the 7 minute mark.
"/all I love it when my top laner with gets absolutely shit on" HOLD UP!!
Now before you start flaming your top laner or go to boards and vent about how there are
"inters/feeders in every game I can't carry smh ritos matchmaking uneven I get retarded cumshit degenerates in every game"
why don't you take a second and think about WHY this happened.
Chronobreak to 3 minutes
Irelia goes in on Darius because Darius just missed his Q. She tries Eing him for the stun but he loses too much HP to her Q and by a sliver of health he doesn't get stunned. She needs to disengage, but its too late, she already got hit by his W. She flashes and Darius follow flashes, E > Q, and she dies to the bleed. Darius lives with a sliver of health.
Darius shoves in and now he's level 4 and Irelia's level 3. Both back and TP to lane. Irelia's jungler tells her to go on Darius as a bait. Suddenly they get counterganked and Irelia dies trying to bait and her jungler runs for his life. Bam, 0/2/0.
Suddenly she gets some very meaningful advice ("stop feeding idiot"), so she's very glad because she didn't think about that before. Now she just sits under tower and waits for the wave to crash. Suddenly there's a rustle in the bushes behind her... oh no, its Elise.
Bam, without flash she has no hope, she gets dove and they take first tower AND she loses 3 waves of XP. Now she's level 4 and Darius is levell 7. The game is over, Darius dives her as he pleases and is fine to take on a 2v1.
ALTERNATE REALITY
Chronobeak to 3 minutes
Irelia goes in on Darius because he just missed his Q. She Es him for the stun and starts walking up while autoing. He flashes and she instantly follows his flash for first blood. She shoves the wave into tower and now she's level 4 and Darius is level 3.
Both TP back to lane. Suddenly a wild Elise pops out of the brush trying to gank her, but wait, who is that running up from the river. Oh shit, its Kha'Zix. Irelia runs towards Kha and sidesteps Elise's cocoon. With Kha + Irelias CC and damage, they EASILY clean up Elise and Darius who chased too far into the river. Their mid laner who tried roaming to help Darius and Elise gets caught out by your mid Ekko and bam 3 kills instantly in your teams pocket.
After those kills they group and easily take mid tower, while a level 4 darius now has to lane against a Sheen+Tabis Irelia who's level 6. The game is over.
The Point
League is a game of moments, and on the boards I've seen over and over people saying things like "but my team mate fed this many times blah blah they're brainless how do I get matched with them etc". This is because not EVERYONE PLAYS THE GAME THE SAME WAY. That doesn't mean one player is better than the other, it means that you have BOTH ACHIEVED THE SAME ELO via different types of play.
Take two people in gold (me and my cousin, for example): I play the calm game - I generally have few deaths and a lot of CS (maybe not on this account, don't remember). I like to make rotations and control vision/go for towers. I however SUCK at team fighting, seriously, I'm so shit at target selection and I RARELY punish my opponent's mistakes. I ALWAYS respect people's roams because I ALWAYS roam.
Now take my cousin, also in gold. He CONSTANTLY shuts down his laner. It's not even funny how many games he'll go 10/0 by the 15 minute mark. However, he's VERY VERY aggressive. Some games he'll be 10/0, some games he'll be 0/5. Also the later the game goes, the worse it gets for him because he has REALLY good mechanics and teamfighting, but goes wayy too aggressive late game and can give up objectives to go for "big plays". He gets first blood like 90% of games, but if he doesn't he gets shit no because he keeps going overly aggressive trying to get a kill, and gets ganked so often its hard to count (and without kills he cant 2v1 like he normally does).
**Is one player better than the other? Nope. We are both in the same elo because we both are at the same skill level OVERALL. **
Do we both get flamed? YES. I get flamed for "being useless" while he gets flamed for "feeding" or "getting caught".
Pretty much, people have different playstyles, and EACH playstyle can be used to reach any Elo. Let me give a few examples of comparable players:
Faker vs Apdo
Faker relies on shitting all over his lane opponent and mechanically outplaying any ganks. He plays HYPER aggressive and it often works for him because he's very good overall. But he also has a lot of games where he feeds his ass off. **I know, even Faker himself feeds his ass off (even in competitive). **
Apdo on the other hand plays safe scaling champions. He plays the slow and steady game and makes good rotations and plays mind games with his opponent. He probably has better awareness of the enemy jungler and better rotations than Faker - but he's not as good mechanically and if his team loses the game too quickly he can't carry.
**BOTH players seamlessly hit Rank 1 challenger in Korea, with completely different playstyles. If I was Apdo would I flame Faker because he died twice in lane? No, because in the previous game his play style probably make him go 10/0 **
Nightblue3 vs Trick2g Both players generally hover around Diamond 1 - High masters/challenger. Trick2g 100% relies on rotational gameplay and focusing on drakes/baron/towers. He doesn't care about kills and rarely wants to teamfight. He just focuses on invading and shutting the opposing jungler down via counterjungling.
Nightblue3 on the other hand, EVEN when he's not smurfing, relies on getting tons of ganks off and just killing his opponents over and over. He understands lane matchups and times summoners, but he uses that information for more kills. These kills create pressure that Trick2g creates via split pushing.
Completely different play styles, but whos to say one is better than the other?
DISCLAIMER: The only time your team mates ACTUALLY hold you back is when you're challenger 1000 lp and Riot matches you with 300lp masters players against other 600lp challenger players. Pretty much its only uneven in very HIGH tiers of play where YOUR the person "boosting" your whole team's MMR.
So how do you win more games? By understanding that league is a game, that especially early, lies on a knife's edge, lets you think differently about your team mates. Maybe your team mate isn't feeding because "they're braindead", but maybe because they found themselves in a circumstance which was unforgiving.
So instead of looking to delegate blame out on your team mates, you can instead focus on trying to WIN the game - even if that means getting the "feeder" back into the game. Don't lose hope in your team mates and you won't get tilted.
**TL;DR: **Matchmaking is not uneven in 90% of games (under Diamond 3). League is a game of moments and one mistake/descision can change the WHOLE course of the game. Maybe if that descision went in a VERY SLIGHTLY different direction the whole game would be turned up on its head. Maybe the "feeder" would've carried if he didn't die the first time. Maybe the "hard carry" on their team will be the feeder the next game because their aggression doesn't pan out.
Some players are passive, and they are never "the feeder", but it also means they are never "the carry" either. Every player doesn't play your playstyle, and they've reached YOUR ELO with THEIR playstyle, so it means that your playstyle isn't inherently better than theirs.
