It would be a fun skill to use, but all the things you would give up would make it near as damned useless.
Aye. MVAM, whilst being "cool" to look at, made absolutely zero sense. Not only are you dividing your energy, shields and firepower by the factor of 3: The fact that the separated parts are much easier to destroy also means you'll lose a full 1/3 of your overall firepower every time your opponent manages to disable or destroy one of the individual targets.
Still, logic holes aside, it was a good episode and I really like ship design (of the entire vessel, not in MVAM), so I'm glad it's already in the game.
