Sorry, but what?
Zandalari Regeneratin is a glorified bandage. It breaks on literally any form of damage, including DoTs, and you have to stand still to cast it. The first tick of healing also comes in AFTER the first 1 second of the cast. So if the zandalari gets auto attacked or takes dot damage within the first 1 second, he gets zero healing. The ability is absolutely trash and unusable in combat unless you’re a paladin with divine shield ready. The Draenei’s heal is instant cast, can be used on other players, and doesn’t break to damage. It’s far superior to Zandalari’s unless you somehow can’t afford to use your own food in between pulls (???).
Also, Regeneratin’ did get nerfed after all the Alliance whining, going from 4 seconds to 6 seconds to reach full hp within days of it hitting the PTR. Get your facts right.
