Well the question remains, why do we want to see huge masses of upgraded infantry? I already seem to miss vanilla infantry battling it out.
Limits on infantry, people equip whole army with upgraded stuff because it's usualy 14 inf , 2 rows in launcher.
In the past there were around 40 inf squads half of them not upgraded because you couldn't afford so much munition so the rest was non upgraded.
So you don't see vanilla grens and rifles battling it out because having those additional 20 inf squads would cost pp from oversupply.
(and there was more manpower i think aswell, so you were able to have alot more inf than currently)
