Not really the majority of mainline infantry remained the same for years.
Grenadiers, Riflemen and Conscripts have only saw minor changes even up to now.
That is a strong indication that thing where about right as far as early infantry play was concern.
The balance of the game as hole is rather irrelevant to early game infantry play.
I am not suggesting to return to the past, I suggesting to make use what was learned in the past as guideline for improving the game.
Power level of main line infantry changes according to the different units revolving around them. It's not just about engages on the early game, it's also about how the investment on those unit will have a repercussion through out the game.
-Grenadiers are the ones which saw the least of changes (pop and rifle grenade adjustment), even if the biggest change was more generally applied (squad formation).
-Conscripts were reworked. Oorah, flare, molotov, vet, pop and their weapon profile.
-Riflemen saw changes to scaling. Most popular commander got nerfed (Elite and flamer) as well as bulletin stacking (triple +10% vet gaining). Bar/1919 saw changes. Smoke grenades were removed.
If you only care about early game infantry play, then it's just shortsighted. If you only care about infantry play, it's just shortsighted. MG, indirect and light vehicles all play a role in the early game.
Even if you care about only early game infantry engagements without taking into account any other unit (vacuum is bad if we talk about balance), the only balanced match was Conscript vs Grenadiers. If grenadiers vs Riflemen was balanced, OH wouldn't had received a T0 MG42, a buffed pio and an increased starting mp. In contrast, USF wouldn't had received a mortar, smoke wouldn't had been removed from them, offensive scaling wouldn't had been tone down nor their light shock units or officers nerfed down.
I am not suggesting to return to the past, I suggesting to make use what was learned in the past as guideline for improving the game.
And what should that be? Cause all that fancy word about weapon profiles didn't reflect INGAME nor the early game infantry play was balanced.
