Bran not using any abilities; will not heal

I noticed while having Brann in tank mode that if I engage something and he is out of line of sight for it, he then ignores that thing even if I run it back to him. It would be good, for Tank Brann, to have some kind of button to force him to engage first. This would also help him keep aggro on stuff!

Still happening and sometimes even happens mid pull

it’s so annoying, hes so inconsistent and will yell at me to not go down but isn’t dropping any heals at all, he is legit terrible.

Just happened on the last boss. No pots, no abilities used.

This is still a random occurrence. I haven’t seen it in a few weeks, but I just pulled a bunch of stuff in T11 Excavation Site delve. Bran did a whopping 215k dps. Looking at the details he used: Volley, Multi-shot, Aimed Shot, Rapid Fire, and Auto Shot.
