Are you fucking stupid? We're lucky we can do anything while disarmed. Most melee classes get completely screwed any time they get dismantled; we can still use our major CC's and peel for healers through CoI, Grip and HC.
Disarm mechanics are there as a soft-CC to melee classes, in the same way that Silences CC casters. Allowing a class to continue to function through this type of CC would make them incredibly overpowered (more so than we already are).
