And why would I do that - just to confirm an obvious fact thralls do use food to heal themselves? That was not the point I was making. You “boss experiment” is irrelevant because in this case boss hits hard, but it also hits slow and you have ample time to re-aggro him on you to give you thrall some time to heal.
When a wave of 10 attackers pounces at you all at once - your feasts and roasted hunches won’t make any substantial difference because healing will be constantly interrupted by damage. You seem to be unaware FUNCOM just removed almost all hyper armor from weapon swings - and now your best thrall can be stunlocked to death by a bunch of naked slaves (who, by the blessing of Funcoms glorious game designers, hit like a truck even on Purge level I)

There is only one boss fight that can more or less replicate new purge fights - Thag fight. And guess what - it had the same problems - your thrall could be constantly stunlocked by summoned skeletons and Thag himself, resulting in a loss of fully leveled and geared level 20 thrall, who could otherwise single-handedly take down a boss like Scorpion or Spider
