Kassadin's NEEDS to be buffed in 5.5...
I would not have minded the changes made to his R, but Kassadin is proving to be hard to play in this patch... it gets easier to engage at level 16, but by the time that happens, i'm either starved or unable to compete with the enemy. I suggest that he receives a buff to his riftwalk as he has become too weak early game to do anything. a 450 ranged rift walk is not enough. If not 700 or 600 range, why not 550 or 575? he NEEDS it. His stats are not meant to be a tank, though he can be a bruiser mid/late game. His early game has been crippled to the point where he is no longer a viable pick. If he can receive a buff to his riftwalk OR to his base stats/stats per level, it would help balance him. I can't even play him effectively anymore. PLEASE RIOT!
