The drawbacks of skipping T2 are so minor now that it's just not worth 200 MP 20 FU any more.
Personally I think a large part in this is the Allies not adjusting their build orders yet (which is to be expected, it's only been just over a week). Not having a Pak is most certainly a drawback, just one that hasn't been exploited very well yet.
Soviets still seem to almost always go for their trusted T-70, but that build order plays right into the hands of the (Assgrens into) Panzerschrecks into Ostwind. If Soviets got the M5 quad instead, it'd hardcounter the Schrecks pretty well while leaving more fuel to get an SU-76 or T-34 to help counter the Ostwind.
Every Allied faction has access to a mobile suppression half track now, they just have to start using them to counter the Schrecks. Players should be given time to figure out natural counters for the stuff that is strong but not blatantly broken, and if after some weeks it turns out the T2 skipping is too strong regardless we can have a look at artificially restricting it (in which case I'd prefer to just make both T2 building or BP2 a requirement for Schrecks).
