@Xypherous: Since you're adding an item that adds "mana-steal", what does that say about mana burn?
We all know mana burn was removed from Wit's End because it was toxic against tanks, but with the upcoming Essence Reaper causing its wielders to restore mana per attack, this makes me wonder if mana burn may make some kind of return in the future.
Now, to avoid making it too powerful against low-mana tanks, I would change it to burn a percentage of the target's current mana per blow instead of a flat amount of mana. Against targets with low mana, it would basically have no effect, while against high mana stackers like Ryze or Anivia or Blue Ezreal it would ruin them.
Any thoughts?
