Why would you want to hit the enemy ship from multiple sides?
The way the game is designed you want to try to focus all your fire into a single shield facing.
Any ship with MVAM could be more of a support DPS role than pure DPS role; the other ships in the fleet could easily open up shields and no matter where you are, you have access to the open shield quadrant. Tactically speaking, it can also improve overall damage output on multiple fronts; you have two sections pouding one quadrant while one section diverts fire, decoy-style.
I doubt we'll see it happen though as the AI on the ground being as bad as it is (with all due respect to the devs, I'm sick of seeing them stuck in doors all the time), I don't think we're ready for a MVAM just yet. Would it be nice? Sure.
But it would also have to have hefty penalties for it's use. I mean, one section blows up... what do you do to recombine the ship?
