Riot needs to learn how to buff certain champions to diminish the strength (OP'ness) of others.
Champs are always cycling through OP > UP > underplayed > OP > UP... Riot needs to learn to reach out to the champions that aren't being played and ones with old kits and fix them so they're all playable making every champ in league on the same level, otherwise you could just keep nerfing the shit out of anything that becomes popular and then wait for the next popular thing to arise.
Here's a little tip: back in season 2 most mid laners had at least 1 100% ap ratio. Now? everyone of them has been nerfed to 70-60% ratios. The game was still just as balanced as it is now but you see the trend riot is making?
's release, but back in 2011/2012 I had a high school friend who was in Master and offered to play with me and even give me some coaching. I downloaded and played one game, then decided I liked Xbox more.

as my main jungler now, I realize champs like her are part of the problem, but dammit, why does she have to be so damn fun AND powerful?
