Yes and I have given you multiple specific examples of that design, which you have continually ignored. Cons are more survivable, cheaper to reinforce, they have oorah. All 3 of those things directly apply to helping with use of the ppsh upgrade
those advantages apply to the base conscript vs volksgrenadier matchup yet volks are still considered superior to base conscripts...
if base volk > base cons and MP40 upgrade >>> ppsh upgrade then volk + mp40 > cons + ppsh
unless you assume some sort of synergy... in which case id like you to identify the supposed "synergy" between cons ppsh that volk mp40 does not present with aswell....
survivability and reinforcement cost dont really help in the base volk vs conscript matchup... the biggest argument you can make here is oorah but volk mp40 have smoke... smoke is just as useful if not more useful that oorah due to its utility..
soo to simplify..
combat advantage? volk mp40
cost efficiency? volk mp40
utility? volk mp40
the one advantage cons ppsh has is more mobility... but the utility advantage offsets it by alot...
