''Recently they nerfed Corki, and Graves because they were the top ranged carries, despite the fact that they were already balanced and needed no changes whatsoever. ''

Well, the nerfs weren't that big, to be perfectly honest. Ez even got buffed in a way.

I'm a bit curious, though, what makes you say they were "perfectly balanced"? It's easy to tell from a player's perspective when something is weak, but how can you be sure said something isn't too strong?
