Am I? I literally went through entire history of this post and you said:
To which i asked
With your reply being
To me that pretty much sounds like you want for airspawn to be moved closer to the battlefield for older planes that are uptiered to certain BR, with justification that they are worse and slower.
Also this is your first time mentioning SPAAs at all.
So you are either forgetting what you argued, or intentionally moving the goal post.
Im gonna assume you just wanted to expand on your original thought even though you never mentioned SPAAs up until this point, and to your idea i say that bringing plane of BR equal to newer SPAA sounds like easy solution since newer CAS planes usually carry modern weapon systems.
This is absurd, remember that this game starts with planes, ground vehicles were later added to help CAS mains farm rp and lions, I literally has a 8 planes one light tank and one SPAA lineup, and I can tell you this is the only correct way to play the game, I can teach you to get better if you asked, bro
