Bloodbath was complete trash, it was worse than foresight and anyone who thinks otherwise is blinded by blood goggles. It was only useful combined with OTHER abilities and only added notable healing when it came to aoe, any single target benefit you got from it was completely negligible unless you REALLY, REALLY wanted to heal yourself above absolutely anything else and blew bloodbath, berserk, back to back inner beasts and equilibrium. In which case you just spent like a bunch of cooldowns and probably misaligned everything all while losing out on a lot of damage just to not die (which could have been accomplished in most situations just by using holmgang)
