When you get 3 lines....

Sucks for me, because I needed:

Ramuh Extreme
Thormarch Extreme
Ultima Bane
T5
T6

All of which won't spawn.

Put it in Party Finder unsynced, and it should fill fast enough. You're not the only one with a Wondrous Tails book containing these trials and raids, after all, and on top of that there are plenty of tanks seeking mount credit, and folks trying to clear coil before they do the new Main Scenario.
