Well, you have only 30 secs to trade your stuff with NPC. NPCs are usually overloaded with various junk and weapons so 30 secs isn't enough time to trade items. You need to sell items one by one and NPCs not always have money and when they have it you still need to scroll down and look for it. So my idea is to increase trade time with NPCs from 30 secs to 2 minutes. If you think it would piss off people because they need to wait 2 minutes for they turn better think about people who are pissed of cause of not enough time to trade your things and because they can't trade their things they need more time to do that, so with 2 minutes trade time many people would be happy IMO. Tell me what do you think about it.
