User blog comment:Darksusanoo/Kassadin...his current state and possible rework ideas/@comment-24363589-20140917005653

I really think that the spellcharge passive is a really nice concept, and would definitely be cooler than the current Kassadin, but it should have more general utility and less of a focus on completely shutting down mages. As an assassin Kassadin is already a fairly harsh lane for slow-moving, teamfight oriented mages.
