What buff/nerf would you like to see happen the most?

This Sona change

Also a reduction in the missile speed of Zeds Q, not because I think he's OP, just to reduce the number of posts about him

Was a little torn between Assassin Ahri and Zed, but I figured my personal enjoyment was worth less than the greater good. Besides, I kinda like Q's movement speed. Even if I play more like Orianna than Ahri now.

(painfully obvious sarcasm)

uh why is a reset on shaco's q when he gets a kill on here?, trist has it and she's a adc idk why they wouldn't give it to shaco when it fits so much better thematically

Nerf Lee Sin, can't use Resonating Strike, Iron Will, or Cripple, but to compensate the damage on the standard abilities are buffed immensely. Put Resonating Strike, Iron Will, Cripple, and Dragonic Pull on a new champion.

I just want a counter for Xin's W. Is that too much?
