The same way you explain Vader leading a bunch of First Order TIEs. You don't.Except thematically the emperor wouldn't use separatist forces he just led the republic to victory over them how would he explain turning around and using them.
Except in the way that both of those factions are controlled by the Sith in general. And Palpatine specifically.In no way does it make sense for droids to be in the Empire faction.
My Vader will never fly alongside an fo anyway so it's a non issue in game.
But I'm not talking in game I'm talking over all narrative, it makes no sense and it goes against Canon from the new books.
There's no arguing the fact the empire kept and used republic ships tarkin flat out says they did, same book shows a rebel group using separatist ships.
The empire does not use vulture droid fighters or whatever the others are called, so it makes no sense for them to be added to the empire faction.
