I did this for a friend of mine with a hunter. First, you need to understand YOUR strengths and weaknesses. Then, figure out if you are better with a shotgun or fusion rifle. Pick one of these void. DON'T FLANK to much. Try baiting them to you. Run with teammates. Camp heavy ammo.Lmg's are GREAT and so is TRUTH. Most importantly though, don't stay in lobbies where you are clearly outclassed. I've done this 4 times now and every time was a little different than before. Best of luck to you and join the thorn club.
