Or axis players would get a PaK 2 minutes sooner then before and actually start using mines instead of spamming LMGs and RGs for a change.
as much as I dislike the lmg42, the grenadier (and ost) are dependent on it. Conscript and rifleman can easily manhandle grenadier in the early game. On a cramped map the ost is constantly fighting an uphill battle.
Most allies light vehicle are practically immune to small arms, with the notable exception of the scout car and the ambulance. The ost might be able to defend with the pak but they are going to lose map control without a light vehicle of their own. Even with the 222 getting the 20mm by default, it's still going to lose horribly against the majority of light vehicle.
