Looking for an MMO that has a Good Trading System

[bacobit]

One of my favorite things about early Runescape was that you could set up a production line with your friends (ex. Someone fishes for lobsters, next person cooks them, and someone sells them outside a boss's lair or something.) Is there something like this available on iOS? I know that's sorta specific, but as long as it has trading I think it'll do just fine. Thank you reading and I hope you can help.
