I recently had a group of RMT, or so they like to be called "Materia makers", down in copperbell mines botting a small room full of the humanoid mobs spirit bonding a bunch of gear.

As soon as you walk in the room one of the guys will randomly invite you to thier group i guess for the added xp bonus. I took the invite after a rounds of me wondering around in there to see what was really up. They actually seem like a legit group expect the all have broken ass English but they do run in an actual LS. I stayed for about 15mins messing with them before i ported out, then out of know where i got a tell from one of the guys in the party asking me if i want any materia for cheap and explained to me they they weren't RMT or gil sellers but were "Materia Makers" and they had a rival RMT group that tries to buy their materia and sell for much higher price than them. lol After awhile he told me if i had any 40+ "fighting jobs" i could come join their party while i sleep. I really wish i able to take some screenshots of the log. I'll have to find out the name of that LS sometime.
