And are you assuming that the luchs should come out at the same time as the Stuart or AEC? Why should that be the case, Stuart and AEC are its natural counter and are still decent vs infantry, there should be a window where the luchs should be effective, otherwise what is the point of having an AI vehicle that arrives at the same time as its hard counter?
Why should OKW enjoy a time during which they can push everyone back to base because their is no effective counter to Luchs? This is not how COH2 works. If your Luchs isnt effective just because their is a counter on the map then you need to L2P and not blame "balance". OKW has no right to get a "counter-free" window of Luchs early game dominance.
Realistically it´s always a mix of Sturms, Volksgrens, Luchs and Raketenwerfer so you can counter everything. AEC, T70 and Stuart need to be very careful when hunting a Luchs because fausts are so easily available for OKW. Just use them to guard your Luchs while using the Luchs to push allied infantry.
