Once you hit 61 you can usually get a capstone in two trees. The middle tree can give you some skills that modify you deception skill, make it more usefull. My Zero is still at lv 52, becaue I was getting frustrated too. I think I just need to toy with his build a bit. Also if you have not got the mission for the Love thumper, a good Roid shield works for a melee build. Also if the close range baddies are getting to be annoying a Spike shield(I like the explosive ones) can be more affective that a Nova, the Spike shield does not have to be depleted to hurt the enemy. A good Turtle sheild is nice too, ignore the penalty to health, Turtle shields can take a lot before it drops. Good luck!
