I saw someone talking about this in-game. I, personally, think this is a great idea. Capture the Flag could be a fun diversion. I envisioned it as talking to someone outside an arena (or the like) and buy a ticket or something. You might then be put on a waiting list so you could run around and still do things and prepare. When a match could start, you might get an onscreen notice that could be clicked to teleport to the arena.
This might all be a little rambling, but I think a PvP option like this could be good for the game. It would satiate the hunger of those who just want to fight others, and it could be a fun game option besides. Best of all, it would leave the outside world as it is, and keep the PvP inside borders.
Is this an idea that might be done soon? I would like to see how it is executed.
Counter-arguments and agreements welcome.
