I think it's good having at least 1 DLC map in the rotation. I think that stops the free game time players from joining, i.e the hackers.
You know you see all these 'noob' posts in the BF forums about hackers, etc, but it's really true. I'm seeing at least 1 hacker per day now, destroying a server. And all this **** you see on the forums from people saying 'uhhh, I've never come across one' is just bs. The system they've implemented is clearly failing. Because to see 1 per day is a massive fail. It just seems like hacking is more endemic now since no one really gives a toss about this game anymore.
And Fanatic, you can vouch for me since you saw the hacker when you joined my server 2 nights ago.
