I feel your pain. I solo'd my way as a healer to 2600 and then dropped down to 2300 afterwards due to a chain of getting wrecked in matches by enemies that played smart & took me out at all times while my team pretty much ignored me and wondered why they didn't get healed. I've pretty much quit again. That game only just brings out an obscene amount of frustration due to players that don't believe in teamwork or team make up because they just want to play Call of Duty.
