I'm still thinking it's our new divine class. The psionic classes have been given: Battlemind, Empath, Monk and Psion.
Likewise, I think Empath is just too good of a name not to use for the psionic leader, unless it really doesn't fit with how they work.I'm praying that the Ardent is divine, in 3.5 it was Psionic in name only and clearly Divine in all fluff, so it needs to be divine.
I played an ardent in late 3.5e, so I'm used to the name. The new ardent is different, but it looks pretty good, too. And the name is an even better fit to the concept now.For me, the name Ardent will take some getting used to.
