So your position here is basically "All Imperial ships should be playable by the Rebels." Because they could always conceivably be stolen?Why even have ****ing factions in the first place then. Might as well let anyone fly any ship they want then if all it takes is one instance to let another faction use a ship. It's called letting factions actually have a sense of theming and identity.Also, why would anyone ever play Empire after that when playing Rebels gets you twice as many ship choices?In canon, the Rebels have stolen a Lambda-shuttle, several Sentinel-class shuttles, a Zeta-shuttle, a TIE Advanced Prototype, and even a Gozanti cruiser. Stolen Imperial ships should be a feature of the Rebels meta-game if the Sabine's TIE experiment works out.
No one (but you) is suggesting all Imp ships be playable by all factions. And if you are talking "thematic" then having a Rebel shuttle makes a ton of sense given how often we see stolen ones being flown.
But, hey, this is a forum and your opinion is completely valid (for you), just as other people's are (even if they make your anus hurt)
