Uhm, they just work as fine as they used to be, they just had their sick range reduced at vet 2. But I add snipers, as my nr. 1 counter against maxims.
Rifle nades dont work anymore thanks to the nerf, its not reliable.
Scout car not really a counter, doesnt make reliable damage to infantry and the same soviet tier has ATGUN.
Flanking is not available sometimes.
The only counters are Mortars/Snipers/LeFH/MortarHalftrack.
Panzer IV is by far the best medium tank out of the sherman and t-34. whether it punching holes in enemy armor or blasting away at infantry the panzer IV can do both putting the sherman and t-34 to shame. i say it deserves a slight buff
