Oh if only actuators worked in a mech game. Oh how much kicking I would do. I would be like the Black Knight of monty python. Kicking at my foe once my arms were gone.
Of course, as a clanner you'd be in trouble with any physical attack as it's frowned on as dishonourable by you guys.... hence the reason most every Clan omnimech has weapons pods instead of battlespikes like the old Awesome had.
Of the top of my head the only reason that some omnis had hands at all was to pick stuff up and run away, or help loading/unloading stuff.
