Well, from my experience: SPAA die by tanks mostly late game where people mass spawn them because the game is already unplayable in a tank due to CAS infestation and because they are low on SP.
In other words - their team is most likely getting pushed back and they also know that staying at spawn means an imminent death. These 2 coupled together means SPAAs become very vulnerable to enemy tanks going forward. And BTW these SPAAs go forward to help their own team’s tanks in a futile attempt to turn the tide. But the mode is configured in a way that “turning the tide” is highly unlikely. Essentialy dying oncen without scoring a kill or assist already ruins the entire game as player now has a lot lower chance of spawning CAS, which is especially painful in an uptier - all you needed was 1 action, now you have to kill 2-3 guys.
This means that team taking losses early on is basically destined to lose. I have been in a scenariore where I spawned a tank was unlucky to get smacked by Su-152 with my shell magically curving towards some impenetrable spot every time, I respawn, drive out of spawn, I get CASd, it’s game over already for me within 2,5 minutes.
But I digress. The point is - when the game is not being lost YET, so when SPAA can actually hunt planes, it gets slaughtered by planes anyway. I kill a few SPAA for every time I die to one in a goddamn Wyvern which is big, doesn’t turn, bleeds speed like crazy and is NOT good at taking damage, 1 14,5mm soviet godhammer hit will cripple it or kill it. Yet I kill SPAAs in good numbers unless there are multiple around the same area. Then I will most likely die, but it also usually means most of the map is unprotected as SPAAs can be ignored from outside 1000m range most of the time, especially if you follow the dive-pull up routine, which surprisingly makes you insanely hard to hit as your speed is constantly changing.
