One thing that I (and probably a lot of other people) have often questioned is why there is a gun trading system in zone, but not in era? For example you see a gun that looks cool but it's bad in pk but you didn't know that so you bought it anyways. Boom, just like that, money wasted. It would be so nice if there was some sort of gun trading or a gun refund option (Where you can sell your gun back but only get like 50% of the original price)
