Gold farmers never took root in SWG where crafted equipment was better than anything you could find, this was before the NGE. Not sure about afterwards because I stopped playing when it went live. Eve Online has a different way of dealing with gold farmers and it works well, plus same again all equipment is crafted in Eve unless of course you get very lucky and find officer spawns.
During my time in UO I could go toe to toe with other players by just using GM crafted equipment where as they used vanquashing blades and magic armour. So I can't see why we can not have a MMO where crafted end game equipment is the same as what is found in dungeons and raids.
Your going to get gold sellers in any mmo, its down to the players and devs to make it very unprofitable for them to flourish. Just to note I have played MMO's since UO was released and the first time I see a gold seller was when I had a momment of madness and played WoW. Before that game I had played EQ1 and 2, DAoC, SWG and Eve Online.
I just do not wish to see this game turn into another gear grind fest where you have to traipse through endless dungeons just to hope to get a decent role on a RNG at the end of it all. Just like every other land based MMO thats out there at the moment.
