This is annoying to me..
Stop calling for Nerfs. I see people all the time that have a bad game against a certain champ and then, instead of researching and learning that champs counters, they just call for a nerf. If you want to play well in this game then you have to adapt to the game, not the game to you. That's just how it is. Be versatile. Learn a bunch of different champs. This is not Call of Duty or Halo. It's a strategy game. Be strategic.
