I'm currently running through the core game campaign with members of my gaming group. While we are all having fun and the game does actually seem balanced (at least to me, the Imperial player), the Rebel players have some complaints.

They feel like the game is too punishing for making mistakes, the synergy needed for the Rebel players gives them a disadvantage compared to the Imperial player and generally that the odds are consistently stacked against them despite games coming down to the last turn or so (even when they make non-optimal decisions).

I want to increase their enjoyment of the game, so that they don't have cause for complaint. I have considered letting up on my aggressiveness every game or even intentionally losing but they wouldn't want me to go easy on them.

Does anyone have some suggestions of how things can be played to increase their morale about this? Any tips for Rebel players to improve their strategies?

Above everything I just want them to have fun and I feel like they aren't when they complain. They tell me they enjoy it but there's obviously something about it bothering them enough if they have to complain about it for 15 minutes after every mission.
