First of all, is there any email address, we can send them emails and suggestions?
The idea is to hire services from major towns. An NPC with a horse and a wagon... You can place your items for sale to them, with YOUR desired price and your desired amount of time.
For example I give my merchandise for up to 48-72 hours to a merchant with my desired price and that merchant is travelling all across the world and selling! If there is any successful sales, this npc mailing my money!! When the time expires, the NPC mails back my unsold stuff.
That could be good, for selling your stuff into other alliances!...
When and if they implement houses/towers/castles for guilds and players, we could have our own NPC's doing that job...
I personally highly support the idea of a hireling, especially when we get our housing, mostly for services (such as selling our stuff).
ps: Thats why we also need a better system for tracking npc's in world MAP, so we can track down NPC's with services.
