Haha I really meant it to be quite dumb TBH because Accession is a great JA but the restrictions are horrible.
Yes RDM needs Haste II, not Hastega.
Also, my initial hidden hope would be that RDM could then /SCH and Temper-ga!

Also letting Rdm share/spread FC buff would be awesome in a spell use scenario. call the spell: Enspire +% FC/Recast.

On the other hand:
Increase Corsair buffs, or add 3rd roll of COR is main job.
