guys u dont get it, this mechanism is a turn-off for new people coming into the game. Also the timeouts is not helping casual players that cant make barter alts(cuz they r new to this game). I agree that there should be a timeout for bartering with traders, but not this crazy 30secs thingy that increases with barter skill!
The argument about being self sufficient by farming mobs to get the stuff u need, than why do we need traders at all, juz scrap them, and let the players do the barter trade amongst themselves.... than u have the power players with all their alts, so they are self sufficient, so the noobs get shafted again....
