Free for all PVP sounds SWEET.
Temporary alliances etc. and PVP clans. How sweet to get in a PVP clan, find out that a bunch of them are jerks, join a different one, and then go out and destroy your old clan mwahaha. I also LOVE the idea of being able to TALK to your opponents. I suspect a TON of trash talking but hell, I am sick of the night elf rogues in WOW that gank you when you're low, and then run away. At least now I can whisper the person and call them a chicken unless they come back to duel fairly.
