Please, don't be mean. After all you have to agree that some units got buffed quite hard and are on the OP side like Falls or heavies.
Heavies were much stronger in the past for the sole reason that you could get multiple of them.
Falls were batshit insane with base 0.75 rec acc and completely insane scaling.
They weren't buffed to the op state, they returned to it and are now going down again, until balanced.
PG coming earlier improves variety, but on the other hand it gives you stronger infantry earlier, which is a form of power creep, even if small.
No, its timing change. Their power level is relatively the same, however they synergize better with vehicles now. Its another unit that was incomparably stronger in the past then it is now.
Ppsh cons are less appealing against wehrmacht as PG who come earlier counter them well. Assgrens needed a buff, but now they are a very early strong infantry, have 5 smg and sprint and make Ppsh upgrade look embarassing. Similar 5 men smg squads have been made available to other factions early as well.
PPSH arrived at 3CP for years, they were always coming up against PGs, due to own stats and ability combinations, they were also much stronger in the past.
Ass grens released in such a broken OP state, relic had to slap 50 muni on initial call-in as a hot-fix just to not break the game completely until balance patch came.
PPSH cons can go toe to toe with ass grens, especially when vetted due to rec acc scaling they have.
Bunch of infantry got some minor buffs or changes to vet that increased their lethality or improved survivability which is more or less balanced against infantry, but when this buffed infantry faces a MG or even a single squad has ATG in the firing range, there's a high chance it's a dead teamweapon.
Team weapons, ost specifically, used to be 3 man crews and there was a time, when HMG42 could not be flanked by anything as any amount of infantry, even advancing from opposed ends of firing arc would be instantly pinned, when flanked all weapon teams went down fast to CQC troops. ATGs were always dead when anything came close to them and you couldn't push it away.
Regarding infantry, ALL of infantry units in game, with exception of Conscripts, Grenadiers and Partisans had their veterancy severely nerfed over time.
To deter an enemy vehicle from advancing, due to the aim time and animations and despite your best effort, your ATG may come within firing range of enemy infantry. The damage that you inflict to their infantry is incomparably lower than that dealt to the teamweapon.
Because base weapon crews have 1.25 acc modifier, so they are easier to hit, because weapon DPS of most units was nerfed to the point, where flanking wasn't rewarding and team weapons crews could just facetank flanks.
As Obersoldaten can be implemented in the build order quicker, there was a surge of elite infantry compositions in teamgames. Even if their upgrade is hidden behind full tech, you already have the unit in your army composition. Was it available later, you would already have that slot filled by another Volk squad and wouldn't build that Ober squad. This results in stronger infantry itself and stronger army compositions.
There was a time, when getting obersoldaten for OKW meant allies were no longer able to engage with infantry and had to use vehicles against them exclusively, because obers would always win, suppress passively and murderfuck squads on retreat, regardless of health, because they had massive bonus accuracy against retreating units. Obers are much weaker nowadays then they used to be.
Other elite infantries used to be cheaper and had stronger weapons and/or scaling, or even powerful ability that was removed(shock troops for example).
Again, out of all units in game, exclusively stock conscripts, T34/76 and Jackson are stronger now then they were in the past, every single other unit in the game used to be in much stronger state.
There is no power creep, never was.
There is just one salty axis fanboy who wants to have allied toys, but refuses to play allies and labels everything that is capable of killing grens and P4s, regardless how much higher cost investment it is as power creep.
