tl;dr of Vladimir's likes/dislikes
 * We like his I, Q, W and R.
 * Seeing people casting his E just to maintain the stacks looks wrong - something needs to be done about his stack management.
 * His costs need to be less mitigatable by spell vamp.

So... his E now utilizes a full resource bar, like Fury, and depletes slowly. Or, stacks fall-off one at a time. Oh, and it costs a percentage of his current health to cast now. I'm gonna say the scope of his changes is the lowest of the 6?
