Give the CE a sledgehammer (also aurora belt buff I guess)

[Superlagg]

Put a space pole on the CE's RCD, give it magic fix-stuff powers and reduced RCD-Ammo usage, and there you go, CE Sledge.

And the CE's special class-weapon should be some kind of wrench, anyway. Hammers break shit, wrenches fix shit (even though in this game wrenches disassemble things for the most part).
