[GAMEPLAY] Revitalize causing extra damage on Dr. Mundo

On Mundo, if you have taken the revitalize rune, it will cause the HP costs of all of Mundo's abilities to increase, while it will increase the healing from Infected Cleaver (Q), it will still cause "Negative Healing" to happen, however, it will increase the cost of Sadism (R), but not cause it to restore more health.

This is very simple to recreate in the Practice tool; All you need to do is take revitalise on Mundo (as stated) and cast abilities, if you look at the "Bonus Healing" part of revitalise it will have a negative value and will not go up from your ultimate. (same for Passive and Warmogs, but I don't think that's meant to interact with those anyway)
