No offence man, but you are living in lala land. Decently microed shocks handily defeat 2 gren squads 9 times out of 10, and no Soviet player worth his salt will chase a non-lmg gren squad while an lmg gren squad is shooting at him.
yes, but its generally understood that, lmg grens are going to be around. if not, mg42s. shocks can be countered by generally good mg42 and grenadier combo early and later on, just 2 lmg grens.
what tata probably means is that, once you can control their movement, you can control shocks. but obers are effective at all ranges. there's no way to counter them except with overwhelming infantry dps.
there's too much rock paper scissors gameplay argument here, yes obers should counter infantry, but not this hard, not when they are a rifle unit. infantry hardcounters are usually require the stars to be aligned (aka shocks being in close range), slow and steady rate (snipers), or metal boxes (tanks). currently, obers behave like human tanks, often just strolling up and ending infantry fights, unless a lucky mortar hit or grenade.
