Borderlands 2 has it's own fair share of glitches, but honestly I'm pretty sure as it's not game-breaking no one really cares. The Warrior isn't really hard of a fight anyway, but you do you, I suppose.
It's been out for a long time, and I'm sure the devs have other things to work on, I'm pretty sure they're working on Borderlands 3 (or something of the sort, there's already been a tech demo shown I think) and there've been rumors going around about a remaster of the first Borderlands.
