Kassadin

I recently played a few games as Kassadin just to have some fun, but I realized he's actually pretty good. He can do a lot of burst damage and he usually won't run out of mana unless he spams his ultimate. There are a few things that I think should be looked at, however.

His E is kind of annoying. It takes 6 spells to actually cast it, and it doesn't really do anything special besides a slow. I could take someone like Veigar and deal a lot more damage on my Q than Kassadin does with his E. There are 2 things that can be done here. His E should only take 4 spells to cast, or make it around 8 spells, but enemy casts count as 2.

Another problem with him is his ultimate. Late game, the damage in pretty much inexistant. I feel like this ability should have an AP ratio, maybe around 20%, so that the damage doesn't fall off late game and it rewards you better for spamming the ability. Make the range on this ability around 600, but increase the cooldown.
