Um Ahri and Fizz got wrecked by these nerfs...Ahri's damage is horrendous in teamfights now (her AOE damage got butchered) and even if you land charm her harass in lane is significantly lower due to her w nerf. Fizz losing .2 AP ratio really hurt his kill and snowball potential in mid game and hurt his chances of bursting an ADC late game. Zed missile speed on his w hurts a ton and his r shadow is honestly completely useless now that it can't be used for damage. He can be knocked off by any number of abilities and can't get back to the target that is marked without blowing all of his escapes to do so. I haven't seen any of them at all since the nerfs and honestly I think that all of them will fall into disuse.
Kassadin on the other hand got buffed, which is absolutely retarded because he was already the dumbest champion in the game. His q is actually stronger at earlier ranks and only slightly weaker at max rank, while he r got buffed across the board by a huge margin.
Meanwhile Orianna nerfs are still nowhere to be seen despite the fact she has been the strongest pure AP carry for about two years now by a significant margin.
