I played, I think, four matches last night and I'm around 65%. I was over 1.5 for all of them except one I was .95ish. You hardly have to be a pvp God to get it done. Watch the matchmaking as the rosters are filling up and leave if you see any 4+ stacks (maybe even 3+ stacks). And if you get in a match and it's clear you're going to get worked over, just quit. It's quickplay - nobody's gonna care if you dip. Hell, if it's that much of a problem, wait until you queue up with a four or five stack and quit the match if you're not on their team. Assuming they're competent (usually the case, but not always), they should be doing enough killing to keep you alive and just focus on getting shots in and racking up those assists.
