I'm still not entirely clear on what BLU brings to the table in this game, but I've read up on some of their skills like "white wind" and "lucid dreaming" and I'm curious of those abilities can be slotted in my action bar and used while playing as another class in PVE? are BLU abilities like the carryover abilities from the subclasses you would already have once acquired while leveling something like from a Lancer to Dragoon?
