Also, Im suggesting this because if vending skill allow tokens as a payment, players can do something more productive things.
As u see, now fro is not so active, cuz most people are just doing 'selling and buying' all the day. Donate-sell-buy-negotiate.
I myself usually spend most of time to find a buyers to sell my stuff... I think its waste of time. I could do pvp, quest, or something more
fun. But becasue I need to sell or trade my stuff to be geared, I just sit and watch the BC for an hour or more.
If our concern move from 'sell and buy' to something more active things, I think FRO can be more vigorous.
