Iv been asking for squad spacing changes forever, and I gave up a while ago. But if your operating under the idea that Soviets don't have the most squad wipe capable stuff then well I don't really know what to say. The amount of squad wipe or almost squad wipe options available to Soviets puts any Axis counterpart to shame, except for maybe the Sturmtiger.
Let me put it this way; Soviets have tools that wipe more often than not, Axis has tools that do more reliable damage rather than just out right 1 shotting squads.
Y'know, given the choice between having a more reliable chance of wiping squads with regular small arms fire through consistent DPS or being able to occasionally wipe bunched up squads every now and then through RNG, I would definitely pick the former.
Personally I think that Axis has the advantage in this regards. Sure as SU I can wipe a squad if I get lucky with a barrage and score a good hit in the first volley, before my enemy moves, but as OH I can wipe a squad more reliably just by getting a pgren or a couple LMG42s within effective range, with far less need for helpful RNG.
Would you rather be able to get lucky wipes now and then, or be able to reliably wipe through your own tactics?
