Character customization?

 There will be some customization for characters and vehicles but not much. It will be in the form of themed skins. We know they are offering exclusive skins for Rey, Kylo and the Millennium Falcon through pre-order/Deluxe Editon. So there will probably more skins in the game that we can unlock or collect in loot crates.    

As for standard troops as far as I know on maps markings on the clone armors are different colors and the skins on the rebels would change from Hoth and endor as well as the stormtroopers.  Also classes change looks too.  I’m not sure about you being able to change the markings or the outfits yet.
