Feedback:User/Thrashed/Friend to Foe

I'm sorry, this is my first time even posting like this and I don't know how it should be categorized really. I dreamed one night about a mass of players all fighting one common enemy and I mean a real MASS of people. The gist of it was that part of the team/mob fell in combat only to be turned into the undead enemy and then suddenly friend was foe. I wish I could describe it better than that, but it was so much fun suddenly being the enemy and taking on people who were once on your own side. I know there was talk of the maps and playing field being larger with more people in, so I thought I'd mention it.
