In my view it frequently takes considerable effort to take, and extract a cv away from a port captured by the enemy. I don't in any way see that as gaming the game, it's a perfectly legitimate tactic for denying use of it to the enemy.
It's very noticeable that the players who give out the position of "hidden" cv's, or who steer them deleiberatly into trouble, are frequently not the people involved in previously capturing the port or the cv, or defending it as it is extracted. Accordingly, I personally regard such behaviour as beneath contempt, anbd frankly prefer they simply changed sides and stayed so.
I don't mind at all having to hunt for, and kill a hidden cv. I've done it many times, with a few squad mates, and the satisfaction in doing so without recourse to cheating is great.
It seems to me that AH players are increasingly intolerant of anything that doesn't give them instant gratification, that you have lost sight of the fun to be had from effective teamwork, especially of the fleet hunt variety, where a lot of second guessing and deep recce flying is required.
What I find especially repugant these days in AH, and especially on these boards, is the lack of at least an attempt, to see the other players point of view.
