Kassadin Buffs are gonna bust him. Sincerely, Kassadin main
I've been maining Kassadin for 2 seasons and I've played him a good amount near masters elo last season. As it is, he's already really strong. The only thing is that even pros still haven't figured out how to build or play him to his full potential. Specifically the AP buff on his R is extremely unnecessary. I've been playing this champion since season 3. Please just take my word for it that this buff is going to bust him, and I don't want to see my favorite champion nerfed into the ground again as compensation.
After kassadin got reworked I had to wait so many months before he was even remotely viable again. Please don't put me through that again. He's good and he's balanced right now. Please don't break him. If you really want to buff him, give him base MR per level. Touching his abilities aren't going to lead to good places. I can even link a video of Dyrus vouching for me.
Please remove the ap scaling buff on his R. Please do not buff his damage.

Played him top this way. geez,it was funny when clarity was still there
who could use a non-damage related buff anyways.
