So a while back I saw some patch mentioning prioritizing bouncing abilities to better effect players versus pets..
ANet, could ya take another look at this? In the mists @sparring NPCs, against the thief, all my pets will die during the fight (whatev) but once the thief is downed and I re-summon my horde and they eventually all attack the downed thief, if I pop Reaper’s Touch, standing on the thief among all my pets with myself at whatever hp amount missing, I next to never see the regen buff and my pets, full hp freshly summoned mind you, certainly do not need it.
