Sturmpios were okayish last patch, haven't had a chance to play them this patch but IMO they only needed a tiny tone down in terms of DPS so they didn't eat enemies quite as effectively, this seems a bit too far.
Sturmpios' problem is that they raped all soviet non-doctrinal infantry, forcing soviets to spam maxim/sniper. But that should have been fixed buffing conscripts and penals.
Now sturmpios are nerfed, penals are the same and conscripts are even worse. Instead of fixing one problem, they created one more.
