I have operative build. It is custom and nobody but me knows it. There is no fun in using someone elses build. You will be suprised how good custom builds can be. Just try to make one. I beat a lvl 36 when I was lvl 34. He was an operative and had a legendary pistol and shield. I did not. He had the best lvl 35 armor. I beat him going one on one. All because of my build. I do not know if I will keep it secret or sell it.
