U didn't read my damn post. Cons don't face double upgraded inf. They have the least firepower in a vacuum. But coh2 isn't played in a vacuum. The chance of anybody tampering with mainlines either to buff or nerf them is extremely unlikely, so I doubt grens will be buffed. Hence the mg42 shouldn't be touched in its current form. Grens are the most reliable mainlines? Then wtf are volks? 5man squad for 10mp more, after vet 1, it gets better RA than grens making it COMPLETELY superior to grens. 0.9 RA squad vs 0.91 4man squad.
Volks don't get better RA then grens.
Grens have 0.91 RA out of the gate as well.
Later vet RA also favors grens.
Most of DPS focused on 1 model which focuses on opposing models is superior then 2 lower dps weapons focusing on different targets, because you will not be dropping models as reliably and opponent will have higher chance to lose just health instead of models, so no, dual weapons aren't really superior in the way you think you are.
Also, factions able to do it, you remember how you REEEEEE'd about ost being muni heavy faction?
Well guess what, these factions you complain about are even more muni heavy.
And while there is nothing wrong with hmg42, there is also nothing wrong with grens and their performance against much more expensive squads who have invested twice the ammo on their upgrades AND more menpower AND some fuel as well, so unless you are just a-move gren spamming blobber(which you are, lets be honest here), any issues with grens vs other infantries come from L2P.
