Proposed Kassadin buff
Between his E taking mana AND charges, and his ult having an insanely long reset time between cost to use, he has some of the worst waveclear without either going oom or foregoing his ult for the next 8 seconds. For a roamer who lost his roaming power and now can't push TO roam, he's not doing so hot.
I propose that if he ults onto his current location for some bonus damage or waveclear, it use the base mana cost and not the multiplied mana cost.
