User blog comment:Willbachbakal/(Champion Rework) Kassadin, the Void Walker/@comment-1876049-20150302010607

I'm not too keen. I mean, I like SOME aspects, but I think that someone who plays Kassadin WANTS to be teleporting continuously all over the place, not just phase through stuff. I suppose it is harder to balance like that, but I think the teleporting is really the core of Kassadin's fantasy (not just mobility, but teleporting).

I dunno, I think Kassadin's ult can simply be balanced by giving it a high mana cost and refunding a considerable percentage of it if he hits an enemy with it. That way he can no longer use it as easily to escape or juke opponents.
