Please no. Dont trade power for duration. Everyone is so focused on how to make the heal better. Its reason for exisitng is to help your co tank survive damage. Watering it down will just remove wars off tank support. If war support goes down, its just going to be less desirable. Thats just a nerf and will hurt wars. We are already the bottom in popularity and most meta opinions. Nerfing our raid support so you can have dungeon blood bath back (when we are the strongest dungeon tank in the game) is not a good idea.
