So squads are one of those things that are simply very difficult to have work in a multi-payer game, even if the game rewards it and the players actually WANT to stick together, it can become very difficult to do so.
Think about NS1, you leave the base with a couple buddies, venture deep into alien infested territory far from your base. A skulk attacks, kills 2 of the 3 marines, and then the last marine is left all lone, certain to not find any more friends before he faces another skulk.
But the problem isn't being about to "find" your friends again, in NS1 we had a mini-map which worked fairly well. The problem is by the time that last marines died and respawns, his friends from the original squad have long since re-spawned and left the base again.
So how about this: all marines have the ability to revive recently fallen marines? Like a medic skill, obviously it would take some time so u couldn't do it in the middle of a fight, but if u managed to kill the skulk, you could keep your squad together by reviving them. This should create a much more cohesive squad feeling I think.
