I think you should loose more then one point for leaving a pvp battle early. As it sits right now there is no penalty for quitting.
And we need more people to do pvp events. Maybe more stuff can be added into the pvp coin vendors( maybe some lower costing deco items that you cant get anywhere else)

How about a Carpet Dye Tub as a pvp coin gift. That would be awesome and I would definately join pvp to save up for one.
