pretty much. but you also have to do an individual HP for each piece, and you also have to line up the two parts of the ship in the MVAM script which is kinda trial and error.
It's not that tough though, really. Just adds more work. Well worth it though.
I should note though, that on a connie, saucer sep was said by Gene to be a last ditch effort to save lives. It needs a starbase to put it back together.
