@Riot Could we have some small changes to Kassadin before the assassin update?

For example, the number of stacks required for Kassadin's Force Pulse (E) is a bit high. Could we have it reduced to 4-5 stacks? It does a good bit of damage, but most other champions have more useful abilities which are more readily available than Kassadin's force pulse.

It doesn't make much sense for it to be so high, as you've still got a 6 second cooldown and a stack requirement for use of the ability.

I can understand his damage being mediocre in comparison to other assassins, as he's one of the highest mobility champions in the game, but could we please have some usability changes?
