@Riot, can we at least have this much of a buff to kassadin?

I've been playing a lot of kassadin lately, and I've been riftskipping all over the place bursting people down. I think that one thing he needs to make him meta again is this change:

R: Riftwalk

With each cast of riftwalk, it's range is reduced by 50, stacking up to 4 times.

Original cast range is now 700 (Old Range).
