My Opinion on the Ahri Nerf
So, I'll try to make this quick. Main point is, I'm happy with the changes that are being made.
Ahri is supposed to be able to duck in and out of fights, hitting charm to disable carries, and burst them down with Q, using W and R for some added damage. What Ahri is, at least in the hands of a less experienced player, is a champion that just goes in. She goes in, does a lot of lock on damage with W and R, hits a Q for AoE damage, and gets out of there easily. Maybe hitting a charm on the way.
The shift in power from her lock-on abilities to her charm is the way to go, I'd say. It reshapes her identity, and honestly doesn't make her that much weaker if you're playing her right. I max E second anyway, so this is almost a buff to me.
Experience, if anyone is wondering: 500+ Ahri games, mained her since S4
