Vayne, Akali, and Teemo top,
We see you. We know what's going to happen when you claim you're going to carry the game. Yes we are still looking at you when you're 2/7 going into mid game where team fighting happens.
I'm not against those champions playing top, but when your team needs a tank, top lane is looked to first, then the jungler. I could say the same thing about those "pro" Kha'zix, Rengar, and Shaco players. Don't be selfish this is a team game. Also thanks to damage creep tanks are pretty powerful right now anyways.
In all honesty there needs to be PSA about supports filling out what the team needs. It's not realistic because they are always 3 levels behind everyone unless they're KSing, and they do not build like other lanes. They're support. I'm tired of being in game, and getting asked to be the only tank on the team.
Do not expect your support to solely fill out that AP you're missing or that tankiness you need. They can assist in team composition, but they aren't capable of carrying that on their own. A team full of glass cannons and a Leona is not going to cut it against a competent team who filled out what they were missing. A Karma support on a team full of AD isn't going to be doing enough damage as a traditional AP laner.
Think about these things and save yourself 20 minutes.
