PLS read again more carefully:
Now if in your opinion ATGs are the intended counter vs Brumbar and KV-8, pls make present you arguments or are replay demonstrating the "intended" use of ATG to counter these vehicles.
Following that logic, snipers are not intended counters of mainline infnatries, because mainline infantries will run them down and kill snipers, before they will be able to wipe any mainline infantry squad.
Distance is also a major factor in hardcountering you know.
SU-85 is hardcounter to panther that is longer then 50 range away.
At 50 and less, its the panther that hardcounters SU due to similar RoF, but 50% larger health.
You're arguing semantics or ignoring completely how units with range advantage are supposed to be used and why keeping that range is critical for them.
