I just dont see what alternatives there are. Yes SLAMRAAM spam would be annoying, but no more annoying than trying to fight Su-25SM3s in the ADATS.
And perhaps it would enable more advanced CAS to be added like Brimstones, ARM, etc etc.
It is an arms race for sure, but we’ve stalled out (both for SPAA and CAS)
Short doing nothing at all and leaving the US and Britain with 7-8km range SAMs (let alone everyone else like Italy with their SPAAG or Israel with nothing at all) there is really only 2 options, these strong, yet shorter range options such as the Supacat HVM or HUMVEE with their respective weapons or things like Sky Sabre or Patriot with extremely high range with some sort of external radar set-up.
The only other option is to make CAP a LOT cheaper, maybe as lower as 200 SP. (maybe slightly higher with ARH) but still. As it stands. I just dont consider Britain (and by extension the US) to have any top tier SAMs and most other nations, bar the Soviets and to a slightly lesser degree, China, to have anything even close to effective top tier SPAA.
10.3 is the max I usually play with Britain these days. Good MBTs, Good SPAA, Good CAS.
Just wish things like the Apache were to be honest, playable, one of the main reasons I worked to get to top tier ground at all, was because I wanted somewhere to play that, that was actually fun.
