The devs responded with a comment on youtube that says this new race character can only be created as a reincarnation and starts at level 70 with own story.
The article mentions what all their racials do:
Psionicists - Swap position with an enemy target that you have a valid path to.
Scouts - Set a trap that immobilizes and deals damage over time.
Mages - For the next 15 seconds 50% less elemental forces will be used for skills.
Bards - While the effect lasts, any buff dispelled by enemies will heal allies for some amount.
Paladins - Restores the timer on all barriers to 10 seconds
Healers - Dispels all control effect on target and grants immunity to them for some time.
Warriors - Temporarily increases Fury and Sustainability.
