Games such as wow, rs, ect... all have a "grand merchant" system. Players simply go to the location and choose to sell/buy one of their items. The do not have to be logged in to sell it or buy it. They simply click the right buttons and it will be delivered to them whenever a seller/buyer gets to it.
Can you imagine how much more enjoyable KO would be with this kinda system? F2P users would have a chance to log in during peak hours, gamersfirst would most likely get more subscriptions since more people would be playing and focusing on leveling, and the game wouldnt bog down during peak times. No more 5-6 hours looking for a decent price on something.
What ye think?
