sorry to hear about your frustration. I personally would rather see a heavier connection-based match making, but I understand why some sort of SBMM is needed. I'm not a great PvP player, but my advice is to continue playing with your group of friends. Try to stick with at least 1 or 2 other team members, but let them lead the way. You'll get some clean up kills from them, and may even steal a few. If you die and respawn away from the team, I'd suggest staying on the outer edges of the map until you find a teammate to run with. Play really conservative if you have to until getting more and more comfortable. If you end up getting only 6 kills, but limit your deaths to just 5, that's fine. You wont be feeding the enemy team a lot of deaths and feeling guilty for costing your friends the match.
