I bet it'll come if they introduce a Greatsword or a Scythe class. If that doesn't happen, then maybe Marauder unlocks it.
Man... "can't give any further details" in that context sounds a lot like "we aren't planning on doing that right now."
If there were ever a moment I wish I was wrong, it'd be now. I don't even care if not all jobs can be used by all classes. Hell, they can lock melee jobs into DoW classes for all I care. I just don't want to only have one optional role for my preferred class. I'll hope for the best and assume that it's only temporary until they work out the bigger ability balancing, logistics, etc., but I really hope it they don't stick with the 1 to 1 permanently.
