That doesn't make any sense. Nerfs would be followed by other nerfs as well.
The vicious circle is caused by five factions, asymmetrical balance and unreasonable fanboys.
If it was up to the fanboys REEEE, we'd have unstoppable axis factions and immortal, 70 range tigers as, since both sides have fanboys, the ones worshiping Meinstein are much louder.
The first two are accurate tho.
People also compare factions incorrectly, they compare unit X to unit Y of another faction, completely ignoring all the other units, upgrades, unit differences and accessibility, economy and timings within the two factions.
Grens will never stand up to any other infantry then conscripts and tanks will always kill them, high time starting to accept that.
Ost also isn't a holy grail of balance, it was for a brief time about 6 years ago, but it is a past long forgotten.
