We all know this. The molotov is still bad, but thats a different matter. Late game its weighted towards soviets who keep their squads alive to vet 3. As they are pretty durable for what they're worth.
this is a headscratcher as the stock soviet units are across the board worse then lmg grens, regardless of vet.
cons literally have
increased received accuracy and don't close well on stationary lmg grens. shocks and (probably? haven't had good luck with them) guards will beat grens but you're paying more for them.
grens are more costly per model and that is an issue vs say, snipers or things they can't fight back against because a couple of model losses costs more then the same on most other squads but it is supposed to balance out in infantry/infantry combat due to their increased power vs most other squads.
