I use auto-bear cuz it procs anointments. Hopping out of IB counts as action skill end. Not sure if this is intentional but its nice having a 15sec action skill with very fast cooldown.
Plus if I ever find myself short on grenades I can just stay in a little longer and spam the burst nades on IB and instantly refill.
I can almost always hop back into IB after 18 seconds when the 160% splash wears off.
Using auto-bear would be alot more fun and less clunky if we could just hold the action skill button and just summon him like deathtrap, may have to tweak anoints but I think it could be fun
