You need four stacks to get to 360+6% max mana. That amounts to 75+150+300+600 mana. That is a total of 1125 mana. Any cast from there on is 1200 mana. It also takes 20 seconds for the stacks to reset.

So yeah, don't count on Kassadin's ult for damage. It's use is the same as it always has been: mobility. The problem with Kassadin is, like it always was, that he scales really well (good AP ratios) and that he can ignore your frontline completely and just kill your backline and then walk away like nothing happened.

Plus he is weak early game. Don't pick anything stupid against him and you'll be fine.
