Yeah, first game of WFA I noted my opponents bulletin load out and I asked him:

"And M3 spam, right?"
"ye"
Thankfully I was able to win due to his horrible micro I was able to take out 2 T34 with a single Jagdpanzer 4 but even so I was hard pressed to counter the early M3. You maybe screaming to get the Püppchen however the Püppchen way too hard a counter for the early game. Sure if you are lucky and the Soviet player happens to wander into that arc and you then kill it than that is good but what else can you do use that unit for? All of the Ostheer counters to the to the M3 are soft, they can also counter other types of Soviet units (i.e. Penals or support weapons) whilst the Püppchen is only good for one thing weaking yourself to infantry...
So the Püppchen needs a massive buff (maybe a disable of some sorts) or the M3 needs to be hit hard with the nerf bat as its not very fun if you get a Soviet player...
