Basically, (Using kh as an example sense most people know what it is) sense the kh spam is still somewhat prevalent and has planes constantly firing them, landing, re arming, and repeating the process with imunity from their airfield on some maps.
It’s makes any spaa fighting them basically an uphill/losing battle, either by running out of missiles to intercept the kh’s or if there’s multiple planes, just being overwhelmed.
So what if we made re arming cost SP? Lets say its 100-300SP to rearm the aircraft, This would basically counter the airfield strat and have cas actually try to engage in the battle.
(Now if aircraft are able to get a kill at lower tiers, the sp cost is disabled. For higher tiers, Lets say 2-4 kills depending on balance.)
