Just had this game. I totally dominated the early and midgame, capping almost the entire map. Then the Sim city horror started. He built 3-4 Bofos + Mortar and forward assembly.
I used LeFH 10.5, Mortar Carrier, Pak, 2 Panthers and 2 Pgrens with 4 Panzerschrecks but I only managed to destroy 2-3. I then eventually lost from 300-8 to 0-8. Please guys watch this replay and tell me how to counter sim city. At the end I smoked the VP´s multiple times in order to get a cap but still he just used his barrage ability, pinning and wiping all my squads. The LeFH was hard counterd by the stupid all map range counter barrage ability, and even though it got 36 kills with Vet 3 it just is not enough to fight the bofos. At the very end he had enough Popcap to have 1 Churchill, 1 Firefly and multiple Bofos + Mortars. PLEASE guys if you have a good strategy to counter Sim city or if you spot my mistake in that replay let me know. Until then I wont even THINK of playing CoH2 again.
