Would the dev team consider adding training dummies to the lobbies between Palace of the Dead instances? While the content gives you the ability to play jobs you normally don't have leveled, it does not enable you the opportunity to sit and play the job for several minutes against one monster to see how it feels for extended periods of time.

I will use BLM as an example. BLM plays a certain way between level 44 and 59, and then that playstyle DRASTICALLY changes at level 60. However, the heavy movement involved in Palace of the Dead with the exception of the short boss fights does not allow you to properly play the job.

I think a training dummy in the lobby to sit on for several minutes would help some players to distinguish if they would like to level a job based on how it feels at the level cap.
