Why?
Currently both SPAA and Air vehicles have no direct influence on who wins a match, because of the way game modes are designed.
SPAA vehicles have no defence against tanks, they are not danger to them. And yet SPAA have to worry about both Planes and ground vehicles.
Mind you, this whole discussion is about SPAA at top tier. Where we need large maps.
I do fully agree that we need larger maps (imo every single toptier map should be 500m grid at minimum) however, making SPAA invulnerable to basically everything is not the correct way to go.
SPAA does infact threaten tanks, as it makes it harder for enemy team to spawn planes, and in turn easier for your team to spawn planes, which results in tanks getting bombed.
Which is already a thing that happens in top tier…
One side most often having advantage, except right now, SPAA players can’t strategize at all in how they play.
