So. This thing. It doesn't seem balanced to me. I'm level 14 Zer0. I have an okay corrosive SMG for that level and an alright electricity sniper rifle. Run up, unload three clips worth of the SMG into it's eye, barely take down the shield, get in trouble, run for cover to deal with the respawning minions (infinite spawns?). By the time I've cleared a path back to him, the goddamn shield is fully charged again.
What the hell?
And no, I'm not paying for xbl gold just to beat a boss. D:
edit--- got him, see post below.
