Agreed, and I think the addition of free high tier SPAA is the single worst thing for ground battles balance since the addition of ammunition boxes a year ago.
Firstly, to describe the general scene of CAS in Ground Battles, or rather a background on player views of CAS.
CAS balance has always been a highly debated topic, but community opinion has always leaned strongly against CAS. This phenomenon is largely attributable not to the actual realities of CAS balancing, but to the intrinsic bias of Ground players in light of their interests. Here’s a relevant graphic from Data Analysis #5 by @Bruce_R1:
This data, which is of July 2025, clearly shows a massive difference between the popularity of Ground modes compared to Air modes. Why is this relevant? Well, the fact that ground vehicles are much more popular than air vehicles means that many players don’t have CAS aircraft at the same tier as the rest of their ground lineup, especially given the large amount of time/effort needed for research progression. Players of high-tier premium tanks, common at high tier, previously lacked SPAA as well.
The result is a large proportion of Ground players with a vested interest in making CAS as weak as possible. Furthermore, having scarcely played or even never used CAS aircraft, their perception of the effectiveness of CAS aircraft is vastly inflated. Player debate is consequently dominated by biased anti-CAS tirades.
Of course, that is not to say that CAS is perfectly balanced or weak overall. But it is important to note that CAS is much weaker than what average player opinion portrays it as. In reality, CAS is somewhat balanced at most BRs, with both areas of strong and weak performance around certain BRs. At high tier, especially top tier, CAS has been sharply decreasing in power since Leviathans update in June 2025. [/color]
The current environment at top tier for the interaction of air and ground forces is hostile to balance. Among SPAAs, effectivness varies, but stays above a good minimum standard. Among aircraft and helicopters, however, the pattern is the opposite: there are a few top performers such as Su-30SM/SM2 and Mi-28NM, but most CAS aircraft here are weak, performing worse than tank spawns. Is the cost of CAS, then, around 10X the cost of SPAA spawns, a balanced figure? Do the hordes of multi-vehicle SPAAs, free SACLOS and IRCCM AAs, and CAP aircraft lead to balanced or dynamic gameplay? I leave this to your judgement.
