I have found it to be variable, some groups better coordinated, some less so. Though yesterday was the first time in a long time since I've done PvP, I found Adders were just as you described and consistently lost on Adders because of it. But Maelstrom were the most coordinated.

But I've generally found as long as there's somebody in alliance chat giving orders or direction to manage the team most in most matches will follow them. Even if the person yelling isn't the best PvPer in the world, the direction helps. So I figure if in a situation of free for all, it's an option to increase the chances of people not doing that. Not a guaranteed win, but boosts chances. I used to find the same principle in WoW, so hopefully out refugee friends still get on boardm
