I haven't played with anyone on my list, nor have I played the 4v4v4v4, but the squads in Conquest/Rush have really gotten on my nerves. I'll get into a game, join a squad and get stuck with three Recon snipers who do jack shit, die a lot, and subsequently leave. So I get stuck in a squad by myself. When I leave that squad to try to get into another, it just constantly searches for a squad and never puts me in one, or just puts me BACK into a squad on my own.
I'd like to be able to communicate with everyone on my team. Keep the squads for alternative spawn points.
