I always get garbage invites using it. Just leveled bard from 1-50 and used it constantly after level 25. I got zero actual invites, eight garbage invites and one ifrit (lol?) invite. I used the comment "Level BRD Looking for an experience points party."

Garbage invites= Hello, do you need a party? Me: Yes, please. They invite and the party is for war, pld, blm, whm etc AF body quest and ask me to switch to a level 50 job.
