I gotta say, Axton's turret is SO MUCH better than Roland's in BL1. For me, the most significant metric of this is that I actually use Axton's turret. Also, Roland's turret can't get a rocketpod as early.

Also, who love's the Loaders secondary crit boxes which knock the arms off? As far as I'm aware, it works on all of them but the Dozers (from in front) and the 'Angelic guards'?
