Being able to only soft counter cheaper light vehicles is not a strong point but rather a weakness, even members of the MOD realized that the unit is not that good vs vehicles.
Out of all the things you have said on this forum this has to be one of the most retarded things you have ever said and makes me wonder if you are just trying to troll.
Units either fall into three categories
No Damage - Soft Counter - Hard Counter
No one here is advocating for the Ostwind to hard counter vehicles so the only option is for Ostwind to do 0 damage for added suppression which is a bigger weakness than doing small amounts of damage vs vehicles. It would also minimize the Ostwinds ability to inflict manpower bleed. In case you don't understand acting as a soft counter is
a Strength not a weakness.
By your logic then the SdKfz 222 Armored Car should not act as a soft counter to AEC/T-70/Stuart nor should the MG-42/50 Cal HMG soft counter light vehicles then. Nor should Panzerfausts/AT Grenades Soft Counter Vehicles. I guess Panzerfausts are a weakness then. No one makes Grenadiers to counter a T-70 with Panzerfaust the same goes with Ostwind and its ability to
SOFT counter vehicles.
The entire point of a Soft Counter is that yes the unit may be poor in that designated role however it will do
some form of damage and acts as a deterrence. That is exactly what a soft counter is.
However if you know that a Light Vehicle is in play then Ostwind is a safe bet since T4 tanks will be delayed and the extra offensive power the Ostwind provides vs infantry helps more than picking up a Panzer 4 while saving you some fuel for getting a Panther.
However once the enemy player knows that you have an Ostwind they are not going to go balls deep into your lines knowing that a potential threat is there. If you take away the Ostwinds ability to act as a soft counter vs vehicles (lower damage would also reduce its ability to bleed enemies) then it will be skipped for Panzer 4 every single time and will only be used only for AA purposes later on.
