All in all, after reading everyone’s comments about shuttles … I am good either decision Addy makes. When you looks all the different ships the empire has … they don’t really distinquish themselves different from similar models. All TIE’s look the same. All Star Destoryers look the same. Etc.
Ady changing Tyderium is completely justifiable … the same kind of model ship the emperor and Vader uses for a supply shuttle? Doesn’t make sense. By changing that, it fixes that problem and keeps Vader and Emperor’s shuttles as personal shuttles for the top brass.
