I would love to see minion battles, personally. If they added some to the world like WOW did, it would give people a reason to explore the world again. Also, they could have weekly/month tournaments as part of the Golden Saucer when it lands.

Tupsi: It wouldn't force anyone to do anything. I mean, I hate PVP and I don't participate at all. But, that doesn't mean I dislike that it's in the game or that PVPers may get special rewards.
