I think you might mis-seeing the magic. It's almost possible to hack this game since there's super protection or encryption every transaction ( as you can see when you trade item back to your retainer, it slow as hell ).

And about the graphic lag.. you cant blame them because if you blame the lag, when you in Ul'dah you must blame other players too cuz if you said you are lag with only 1 or 2 full PT of RMT.. i think you can do anything in uldah since it a lot more player in the area.

Try to upgrade your PC/Graphic card would help solve your lag issue. And just ignore them. Me too see them and I'm still curious because sometime they just standing still and do nothing...and what's the point of RMT if they just doin nothing lol.
