Who put the Reactor Core in the Hangar Bay?
Seriously. Whose idea at Lucasfilm was that? What a stupid idea.
Did it not occur to anyone in the Old Republic military in the Clone Wars all they had to do was fly into the Droid Ship hangar and fire off a couple Proton Torpedos at the Reactor Core to completely destroy the ship?
Yet we see them plain as day heavy battling at Geonosis and Coruscant in the movies, and then there's the whole Clone Wars TV series where they are some sort of fearsome craft surviving against all the odds. Even Grievous retreats to one at the beginning of Sith.
