From the game play section of their website:

"THRONE AND LIBERTY features a class-free system where your weapons decide your role. Combine and configure two different weapons to maximize strength, defense, and damage." (but not healing?)

Out of the weapon options, only the "wand and tome" offer any sort of healing ability "Leverage curses to deal damage, weaken enemies over time, and heal allies in battle." (healing is the least important?)

All in all, sounds like healing is less than an afterthought in the game. I'll pass and stay here.
