The same thing they did in FFXI with the system available there..."sell" loot runs. Only with WoW's system, it will be monumentally easier for them since they can just "trade" the Rare/Ex loot.
you see, if this was the case, why isnt it already happening in WoW? some high level guilds with content on farm have been known to take non-guild members along, for a fee, and let that person take a desired item (if it drops) yet RMT hasn't set foot into that kind of thing at all, and the fee negotiated is in-game currency (no different from tele-taxis in FF11, only instead of transportation to a particular spot youre paying for what amounts to a dungeon run).
so why would it happen in FF14? if you take an invite to a dungeon from a group of people who are all RMT and youre afraid this will happen....leave the group and find another one. the system in WoW just accomodates for human error and unlucky happenstance. online games have a tendency to be at the mercy of a number of variables, among them the performance of your ISP, the performance of the network in which you use to connect to the outside world, and the natural fluctuations of your local internet network. im sure everyone remembers that it was like to play right as peak JP time came rolling around. all of a sudden a latency of 150-200 would spike to the 500's, sometimes resulting in DC's.
in short, shit happens
and this kind of a system is a great way to deal with those kinds of situations in a way that makes everyone involved happy.
The thing about me is that apparently it's very hard to tell when I'm drunk. So I feel like I'm walking sideways on a UFO and everyone else sees me doing the robot like a pro.
i have bathed in the blood of many. my life was spent well.
