Imagine If for kassadin

I was reading this post about kassadin E and it charge and thought of some what if change to his abilities I don't them to make these change or even considering it I just though that it be fun to share.

1. Changes to his w to give it an additional effect similar to Mordekaiser old Q actually exactly like his old Q :P plus the mana regen of his current w. This would give him some aoe wave clear which is nice and hit give more damage to champ who are alone that 1v1 Meddler said he should excel at.

2. Rework the charge system to his E. Instead of needing all the charge to use the abilities he could instead get bonus effect when he use it with full charge like stronger slow or more damage if the champ is alone.

Of course the number would be changed for balance purpose but these are just some idea I had and i really miss that old Q of Mordekaiser. :P
