Let me start off by saying I ADORE delves. The idea of being able to do single-player content that gives great vault progress and decent ilvl gear is great for people like me with an unpredictable schedule.
BUT… Was Brann ever playtested? What is up with him? Healer Brann is worse than the WORST pug healer you can find with their arms tied behind their back. The idea of him throwing potions is mind-bogglingly stupid - he often throws them in completely idiotic spots, such as off cliffs in water delves like Sinkhole, or today in Kriegval’s rest - INTO the base of a column. Even if you somehow manage to get to them, their heals don’t register. Another thing is him throwing them at the randomest times - when I don’t need healing and am at 99% HP he’ll throw them and by the time I need them, I’ll run into them and they’ll fade out without healing me. Or I may need healing desperately, I pop the hunter’s 2 min cooldown heal… and right afterwards, he throws potions.
Even DPS Brann is incredibly stupid. On classes who have semi-dependable self-heals like Demon Hunter and Death Knight I use DPS Brann, and sometimes after big fights when I need him to pop the campfire… he’ll run and fish/mine/etc to give me 2 low quality materials I don’t need.
Rant over, in short, I hate Brann and wish the worst upon him and I really wish that in Season 2 at least we get a companion who does actual healing instead of throwing potions.
