Even if he chose to put his primary and secondary onto the Mammoth, or similarly to Argus that preferred more assist-like weapons to gunfire, everyone is still considered to have a pistol or two on hand, so they can fire during an attack. In Quibbles case, his attack would probably count as the Mammoth bird's fire. It's all in good fun. And I know Argus will probably mainly be more for Melee. I actually picture his claw arm to extend a good many yards like a claw-arm toy machine to get prizes. I imagine him whipping it towards the enemy to attack, heh.
