This game really doesn't have waves, but two releases meant to fill similar roles. A Wedge Antilles and Rebel Pilots expansion, and a Soontir Fel and Imperial Pilots expansion. Wedge and Fel could be commanders that have command cards that represent calling in fighter and bomber strikes and are likely both budget commanders in the same vein of Leia and Veers. The pilot expansions adding new pilot cards that could be used for vehicles as well as either a Support or Special Forces grouping of figures. Both generic pilot mini sets likely being weak with blaster pistols, like range 1-2, white dice attack, but come with some ability to buff vehicles or repair them. The heavy weapon options for the Imperial pilots probably being the grenade launcher that they have in the classic battlefront game, and possibly a sniper or satchel charge placer. It sort of depends on if they might want to sort of work Inferno Squad into the release. The Rebel pilots likely having the heavy weapon options of the scattergun that they can get in the old Battlefront games and probably some upgrade that you could make use of in Rogue Squadron 3.
The idea is sort of rouge, but it'd be cool to see them in the game, since well it would be nice to have a list built around vehicles with Veers leading the ground forces with Fel sort of leading air forces. And well, I also just want some cool pilot minis on both side, it'd open the door for some cross play/ campaign play between this and X-wing or Armada.
