Why Riot loves to have a handful of champions viable and the rest in the trash can?
If you don't play the current meta champions you lose, as simple as that. Go into a game and play one of the meta champions and you will see how you out damage, out sustain and just be better at everything then the pathetic off meta champion your dumb opponent dared to pick.
Go and see LCS games and you'll see the same fucking champions in every single game, how pathetic can it get when your mid meta was corki-azir every game. Does Riot even have the slightest shame watching how pro games use the same 2 champions in mid lane? absolutely no
I get every game needs to have a meta, things that will be inevitably stronger than the rest, but there is a limit crossed when the meta is that much stronger then off meta that picking something out of meta is even considered troll.
Riot games I know how hard it is for you to balance even the most simple of things, I know, we know, I've been playing this game for 10 years I know you very well as a company and just try at least fucking try to make off meta champions stand a fucking chance.
