Can we please have a turret KDA?
I find that players focus more on kills rather than actual usefulness in regards to how a game went. I get a lot of teammates who go 20/15/7 and go "gg ez" when they haven't even taken their first tower at the end of the game. I have players straight up leaving their lane to attempt to hunt other players when the point of the game is to take the Nexus, not get the most kills. I tend to play top lane and my focus isn't on taking out the enemy, my goal to to have a higher cs count and get to their Nexus first. If they run away at low health, I let them run. I have won my advantage.
This leads to a tangent on players who focus on kills. If you have an advantage, USE IT instead of hunting down players just to get more!
Context: I had a Kindred that was doing really well early game with 10 kills in the first 10 minutes but did NOTHING to help the lanes outside of just killing the enemy champs and farming the jungle and top lane/jungler. i.e: Didn't push lanes, didn't take Dragon, didn't assist on towers. She even took the Rift Herald... like, that's a rant on its own, but I digress. In the end, she became ultimately useless because she never came to help bot lane, which was doing fairly well, (I was ADC, Ezreal/Leona vs Quinn/Nautilus) but we were at a constant stalemate until eventually Quinn took my first tower then started roaming. A lot of people don't understand the importance of towers! It allows other lanes to grab control of the enemy jungle and help rotate those laners to help other lanes, eventually winning the game!
I have no idea how the scaling of champs work, I just know basic strategies of this game (If someone was willing to teach, that would be swell) but eventually Kindred became useless and we got stupidly overpowered with Jax coming in the late game and destroying our towers while my idiot teammates were chasing after the injured Nautilus while Jax was merrily taking top tower without a care.
tl;dr Please Riot, try to encourage players to take towers by giving it its own score. Being 5/2/12 with 3 towers is better than being 20/15/7 with no towers. It encourages people to flame the actually useful members for doing their damn job.
(as percents, if you have done all the dmg of your team, then you have 100% dd),
(the same explanation as before, but kinda reversed)
.
and get snowballed in 10 minutes and carry the team than to pick 
and pray to god botlane doesn't feed 20 kills in 5 minutes.
(Yes, bring on the hate) and she is a strong snowball champion. I play a bit more aggressive in most match ups instead of farming because getting a gold/level lead is more important. Once I get a couple kills and I'm far enough ahead, my lane becomes a death trap for my enemy laner. If he attempts to farm, I can jump on him and delete them near instantly. Eventually, most tanks out scale Riven which is why I play for the early/mid game by getting that lead.
I stick around and whittle down their tower whenever I can.
before his rework, you wanted the laning phase to go on for as long as possible because Darius was useless in teamfights and his rotations were a joke. It was to your advantage to make the most of your extreme laning strength by forcing your opponent to farm CS as far away from his base as possible, so you can keep killing him when he comes back to lane and shut him down. Therefore, it was best to leave his outer turret untouched until you got 7 or so kills from him. It's a similar strategy with 
are generally good at shutting down other champions but bad at roaming, so often they will avoid pushing the tower and will just sit in lane killing their opponent every time they try to CS (although this strategy isn't as popular ever since Teleport became meta, as the losing champion can often just counter this by helping botlane before they get completely shutdown)
is a prime example, until she hit's level 6 and a couple of items, she's really vulnerable, so it's safer to fight under your ttower until then, then use your ult to force the wave to their tower as fast as possible when you need to take it. 
and 
can pull this strategy very effectively as well, for similar reasons to 
can freeze lane if she wants, and get lots of CS, but she can also play kind of like 
, slowly pushing forward until she's forced her opponent up against their turret (and possibly even further than that, cause her passive can spawn tentacles on the enemy turret, and the turret won't attack them).
