Hey,
Is there any good reason why healthstones are not usable to heal through the Xal’Atath Devour affix? Warlocks have one of the worst kit to handle this affix: you need to sacrifice your interrupt if you want to dispel ONLY yourself (and that assuming you don’t line of sight the imp or he does not stay behind like in Dawnbreaker), but on top of that I noticed you cannot heal through it with healthstone. Mortal Coil works, so why not the healthstones?
It is already difficult to get into keys as warlock but during those weeks having a warlock in your group is just a nerf, so it is not very motivating to play…
