League of Legends is NEVER going to be fully balanced
It bugs me when people say "Riot don't nerf so and so forth because LCS BIG PLAYZZ" or "They don't know what the fuck they're doing" even though both are probably somewhat true, it's just doing that would really do fuck all in terms of making "a more diverse game" that Riot dream for (I think, unless they're lying about that too cough Solo Que)
Like if Azir, Ahri, Volibear, whatever the god tier champions are that shred through everything right now got nerfed to IDK, Ryze level and all the other champions stayed the same, pros will just find whats strongest out of the untouched pool of champions and make this new meta and we'll just go through this same cycle of "op" champions, even if champions got buffed, it's just a readjustment in the meta, THERE IS NO MEDIUM OF BALANCE IN LEAGUE, Accept that folks.
