They could just be placeholder names for disciplines they had ideas for though I do recall that there were actually abilities for the arcanist class which would be the 3rd DoM. Never know though they could surprise us with some new classes soon enough, or we might have to wait til 2.0 for it, though it would kind of surprise me since they seem to be doing a bulk of the class adjustments this VU I imagine that afterwards they would be able to expand the DoM and maybe even the DoL list.

Though to go off on another tangent. I think it would be neat if DoL were more like "advanced classes" where you needed one basic DoL at rank 50 before you could dive into the next tier of gathering lol. Not like it has to be mining/logging/fishing kinda thing they could be unique and have something like a land discipline that can discover holes in space and investigate it to find unique relics and items that can be synthed into unique items lol.
