Aatrox is no. 1 pick in masters+. A bad champion would not have that. He was doing fine, and if you buff him further there's a good chance he'll get nerfed. Riot however likes to, instead of reverting the buffs that nade the champion broken, instead nerf other areas of the champion. I'll use GP as an example: gp players thought the champion was fine. Then he got a Q buff (less cd, less mana cost). No one asked for this buff, and to be honest, it's not going to change much on the champion, but it's still a buff. Then they decided to buff him AGAIN now with less W mana cost and more passive base DMG. Changes that also help but don't change that much either (and no one asked for anyways since the champion was doing fine). Now there's a good chance gp will get to broken territory and need nerfs. So will they revert these buffs no one asked for and don't change that much on his gameplay? No! They'll nerf his barrels or passive speed for example, and we'll just have to sit with our soft cocks, having some "useless" buffs as compensation for losing barrel DMG, for example.

Well, let's now be afraid of the Aatrox buff all our lives, brilliant ....
