I hate having tons of heroes on the table as much or more than the next guy, but seeing Legion as a game that's supposed to provide lore is quite off, if you ask me. It's a war game where stats are provided on cards rather than in a book; that's great, and hopefully something that doesn't change. A "Battles of Legion" book that provides additional scenarios with maybe, just maybe thematic army builds could be cool, but it's something I don't expect to see FFG do.
If you want to turn Legion into an RPG, do what I've done and have 3D printed figures you swap in and out as your generic commanders. Captain Mud'ai Bouts has a long list of victories to his name, and Major Grump has a good track record from my last RPQ.
I would like to see the game become more about the troops and units, rather than movie or show characters that only briefly participate in these battles. Jyn, Palpatine, and Sabine earn special ire, because their military contribution is extremely limited, but even Han and Chewie are a bit annoying if we go by Disney's canon. The Jedi characters of the Clone Wars fit because they served as Generals or Commanders far more regularly than others. If we have to get more named characters, I'd love to get ones that actually make sense to have on the battlefield. Lando makes sense, as does Cracken or Ackbar. For the imperials, Tarkin and Thrawn would be great to see on the table. More generic commanders would also be cool, though I'm not sure how they'd differentiate them from the ones we have already.
