Yeah like some people here have said, you can't hit 50 and expect to do all that great right away. If you were smart and had 1k/1k comms, along with a pre-purchased bag, you should have 6 bags with which to get comms out of. That nets you about 2 pieces of centurion and 42 champion comms, not to mention if you're lucky and get an item inside a bag. Then just grind it out for a couple days and pick up a few more pieces, and it should be a lot more even. The other thing is, playing an Operative. It's the squishiest class there is, especially with no expertise. You rely on bursting people down, but against players with champion sets you won't be doing much dmg, on top of the mostly rediculous nerfs the Operative class has suffered. Not that I'll complain, as I still do amazing in PvP with my mostly champion geared Operative, but that's much more a testiment to player skill.
