Again, only true at lower levels. By Rank 400 you've got competent sniper micro and once you get to the top ranks sniper use becomes so good it can decide entire matches. The Maxim has a fast setup time which makes it quite strong offensively but its smaller arc demands a higher level of micro to use effectively. Maxim spam was a viable strategy before SBP revived OKW Mechanized tier. Conscripts beat both Volksgrenadiers and Sturmpioneers early on if they have the favourable position and vice versa.
Sniper is risky. If you have a small 1v1 dark map then sniper could easily get killed and its basically game over then. Sometimes one shot is enough to kill a sniper. Soviet player shouldn't have to come back in the game with a better skill. Here it should be considered that both player has exactly the same skill.
Maxim sometimes suppresses quickly but sometimes doesn't do anything if two or more units come. Then you have no option but to retreat it.
When you consider Conscripts vs Volks or Strums, you have to talk about situations when both are in equal positions. Of course favorable positions have advantages, but that is true for OKW player as well. Then what about the situation when Volks and Strums have got into favorable position? It will make OKW player even stronger. When discussing faction strength you have to assume every condition like position/cover is equal.
