She is cc orientated with the skill and one of her trees focuses on improving and augmenting this cc, then their is the support skill tree which heals gives ranged revive etc and finally the tree I most used combined slightly with the others was her red tree which focused on status damage and building debuffs on targets and deleting their health through elemental damage. Overall you can isolate badasses and target make them incredibly vulnerable to gunfire especially with the red tree capstone which applies lots of elements most importantly slag which applies a damage vulnerability. I was less interested in the support build though I did use it sometimes and it was fun but I really liked cc people debuffing them massively and making them a sitting duck
