So I've had a thought.

Since some of the Ragged Brotherhood members are at Aroway (Made up island, north of Akane Beach) I thought it would be a decent time to give Phoenix Wing Members an opportunity to meet some of the members of said Brotherhood, which would essentially set the rivalry and mutual dislike of the two guilds. I've created a job request which would allow for this:

The plan is for the Ragged Brotherhood members to stay at Aroway for a while, both to find the Lacrima, and fully impose a hold on the island. Depending on how long it takes for one of the members of Phoenix Wing to get back from their job/s, it should be enough time for the Phoenix Wing members to reach Aroway, have a small fight before the members of the Ragged Brotherhood leave with the Lacrima in tow, which would result in a failed job request and a reason for the Phoenix Wing members to dislike the Ragged Brotherhood.
