I think that option to deploy AA is making game a little boring, for example now russian AA is deployed it takes huge chunk of map, a you can use no airforce for big part of game, and that makes it little boring. I think it could be changed a little for example if AA is deployed it could just add AA to fight in its range. Because now only thing that can be used is SEAD foces but they mostly contain of AA and SEAD planes which are useless even more because there are no enemy AA since they re far away to fight so SEAD are absolutley useless most of the time. And because AA covers half of map you mostly can not use CAS.

-So like this SEAD is useless because they dont fight AA and therefore not necessary but are only onse that can be used.
-CAS cant be used because AA is OP
-And you cant play AA or can but they re also useless since they re deployed so nothing can pass by them anyway, (Besides SEAD which is just one squadron)

It just takes some amount of fun from game because most of time you have AA without planes or planes without AA.

-So I recommend to add AA as option to take if its deployed and in vicinity of fight and to make 3 AAs for free or something.
- Or at least to put 2 plane slots and one will be only for SEAD and you will have option to take with normal squadron also SEAD as support and together they can pass trough AA defence. But first i think would be better because you could use dedicated AA against CAS and or have SEAD actually fight radar AA.
