I reckon you should be able to trade gold in game for faction and vice versa. It would help people migratin to and from Pve/Pvp. I have 100k, but since I am doin 99% pvp now i don't need it, which is quiet annoyin.
Well, if you really don't need it I'm accepting donations for my perfect farming axe fund. So, LMK.
Seriously though, I think your idea is a good one. It may give people some reason to go back and play the non-pvp a litttle more too and pump up the economy a little more.
Yeah I like this idea...But the main reason is I always have more faction than I need and I would like to be able to give out faction to my guild when they need it.
