Who Pulled Those Mobs?
Brann's companion AI seems to have gone on the fritz since the recent start of Ghosts of K'aresh, leaving him making questionable choices during Delve runs. Where before, he was decently competent at watching what he was pulling, Brann will now go out of his way to run across rooms and pull entire mob packs that not only were you not in combat with, but you weren't even in danger of walking close to. Players have been reporting bizarre behavior of Brann running amok, and this is on top of his prior issues of standing in suboptimal places - that hasn't stopped either.

Brann, unless he's in Tank Spec, should ideally never pull a pack of mobs on his own. Having Healer Brann suddenly run over to you with a gift of a dozen new friends can easily overwhelm many players, and having NPC intelligence be the reason for your death feels awful when you pulled as much as you knew you could handle.
Speaking of Healing... What Happened to Potions?
Another thing that many players have noted in Season 3 is that Healer Brann seems different - and feels like he's healing for quite a lot less.
While there hasn't been a documented nerf to Brann's healing abilities, Delves seem to be doing significantly more damage, and Healing Potions are mitigating much less. It's much harder to survive with this, coupled with Brann's uncanny ability to run off into the sunset and pull half the Delve.
Can Brann be Fixed in Delves?
No matter how amusing some of these bugs may be, they're far more annoying to most players. Something has clearly gone awry with Brann's combat capabilities since Patch 11.2's launch, and hopefully, Blizzard takes care of it soon - or else Delves might quickly become a chore that frustrates people as they grind out their vaults.
