Either do I but the tooltip was something along the lines of "the okw has many aa solutions available to them such as the flak ht, luch's and base 20mm flak's etc"
It makes sense to have it shoot at planes if the ostheer 222 can do aa since the luchs is basically a beefier 222 with the same gun, they probably removed its aa ability in the end since they had so many stock options with the base flak and schwere auto shooting down planes on release.
It doesn't make sense. Luchs has much worse gun elevation than the 221/2/3 scout cars due to turret design. Honestly, the 222 shouldn't be able to shoot planes either with that dumb turret cover. I can see 221 and 223 being AA, though.
On topic: I like the flavor of salvage instead of cache. OKW floats manpower like no other faction, and giving them caches on top of that is a recipe for disaster.
+1 to caches benefitting builder player only
