i play a DRG, and i noticed that some gears i cannot "need" for and it clearly says its suitable for DRG/LNC. why is that? is that a bug? because i kind of find it frustrating to only be able to "need" gears that's for all diciples of war.

secondly, how does limit break work? as a DRG, should i buff up before i pop it? or is the damage set at a certain amount, does it crit?

thanks!
