Completely random thought that came to my mind with Skyhammer stood in front of me here with the Aerialbots combined with him. Why do the Power Core Combiner drones have faction symbols on them? I see the drones more like the Armada Mini-cons, which Hasbro themselves said "belonged to neither faction" way back when Armada was running. I can see why drone sets are released with Autobots or Decepticons, but it just seems really weird to me to have Skyhammer running around with Autobot symbols on his arms. So yeah, minor nitpick that I've already seen past, but it just seems strange that Hasbro would divide the limb sets into "goodie" and "baddie" sets when the core of the gimmick is the ability to swap out / mix and match.
