News flash - Not EVERY champion has to be good at EVERYTHING.
"We're adding * because champion * currently struggles with it!" - More times than not, it's a champion who is intended to build defensively, and riot effectively giving them more damage, wave clear, or sustain.
If you're not building damage, you should not do damage. It's that simple, tanks are not meant to be asassin's and they shouldnt' be treated as such. CC bot, and front line is what tanks HAVE to be for League to have a successful future. There is no reason why a champion that ONLY builds say... black clever? Should have a point and click ult capable of doing 1.5k+ true damage. That's just absurd.
Solution? Every defensive item you build reduces your damage dealt by a certain %. Tanks are over powered, not skilled, and not balanced.
There isn't any reward to playing high skill cap champions, when you can just play boring braindead sejuani and run around like a mad man.
I know Riot LOVES their LCS, so here's a thought, nobody gives a shit about someone sitting around playing Zac, it's boring. We want to see Nidalee, Lee Sin, Khazix. So fix this garbage, jungle meta is awful, top lane meta is awful. i don't give a fuck about cho gath, maokai. get that garbage out of the game.
