i think this mode would be more interesting if it had combined mechanized forces and some waves composed exclusively of planes (meant to lower the blue bar by pure destruction of tanks), and also the use of MLRS instead of 2 planes at the beginning of each wave as a way to destroy buildings
playing SPAA in this mode is quite boring and something a single person is designed to do bcoz you can destroy a hundred tanks but theres only around 16 planes in total, and enemy ground forces are smashed by helicopters since they are far more effective in a terrain where you cant always see the enemy
if the capture point was the middle of a big city for a new map not only you’d be able to defend against planes while increasing their numbers but also it could create a more interesting urban warfare scenario where tanks have a main role and helicopters requiere more skill to maneuver through buildings so it wont happen that there are 3 helicopters with 100 kills and the rest of the team eating crumbs
