Mechanic job, Edelstein and Leben Mine discussion

This (first picture) is CLEARLY a stand attached to the weapon (indicating massive weight of the weapon, to the point it requires support). You don't move when you're shooting a mounted weapon. Also, anyone getting Frankenroid vibes?

Which means, during a FEW of the skills this job has, the mount will be stationary. So what, ultimates are the same. Doesn't directly relate to "mount that cannot move", does it?
