LOLWUT. At level 50 I destroy with two rocket turrets with shields, most of the time I don't even bother shooting my actual gun. on bosses and tougher enemies I slag them first and then use grenades/rockets to just own face, if the turrets don't beat me to it.
Axton's turret with rockets and shields is insane. I'll admit, it's not that grand without the rockets though...so it depends on what build someone goes for. --- "The turning of the tide always begins with one soldier's decision to head back into the fray."
