well what is your teammate doing? jagdtiger wins guaranteed against isu with same micro so your teammate should focus on killing the atguns and t3485s.
I played a 2v2 on rails against double isu play, we were pushed back until the JT came where we slowly pushed out. I was ostheer and went panthers and joint ops with howitzer and light arty to kill the atguns. JT has free reign
it was rails and metal, both OKW he had the "right" side of the map, fuel point trench with house, I had the open side of the map.
he was against the ISUs, I was fending off KV-1, T34 and shocks - We held middle and my side of most of the match, I was able to push into center a little bit, but couldnt venture over to help him much because I would have gotten flanked hard. He got a King Tiger out but still got pushed back.
there are definitely a few things I could've done better, but I was hoping there was something better than being forced to go JT.
