If we do get it, it'll be a healer.

As a DPS of any kind it would feel too similar to MNK. As a tank it wouldn't really make any sense. As a healer though, it would be one of the only opportunities for them to give us a TP based healing job. Given how the devs are struggling to differentiate the MP based healers this would be a really easy one to make unique simply due to having a different resource system.
