Im a big fan of choice, Not a huge pvp'er but I have found it very fun a times, but only in open world, GW2 pvp to me was stupid.
Id like to see player run tourneys, and Id like for some pvp zone, not an instance at some point, with possible loot, a lot can be done not to make it a gankers paradise, while allowing people to have some pvp fun, Options are always nice, maybe a function that allows FC's to go to war or feud, and then those players in their respective FCs are flagged to pvp each other for a week, I'd like to see it all, Eq2 PVP was realm vs realm and I had a LOT of fun going over to Freeport and sneaking up on guys, well done pvp makes it so you don't get bored, something that allows players to fight each other, and some method of rewards would be good, I really do like the war idea, or maybe a permanent zone that your FC gets so much gil or items for holding for so long, if all they offer is instanced pvp I most likely wont do much of it.
