I like the 3 new maps a lot. Though I wish more DLC would come out. I would like to see the elite maps put into regular rotation with the other maps, if only for more variety.
That said, Overwatch may be the best map ever when playing HQ. I routinely rack up 50 plus kills and you often go to the time limit because some of the HQ's are so hard to capture.
For the large maps though, I would appreciate some more spawn points. It takes a really long time to get from A to B on Overwatch when you're playing Demolition. Sometimes it seems like you run for 2 minutes just to get shot and and do it all over again. But i diregress.
The Gun Games are fun. But I freak'n can't stand 1 in the chamber, ESPECIALLY on a larger map. I have been on and been stuck watching the last two guys just camp each other for 5 minutes, and that's just lame. I can't stand that game.
