ISU-152 is not useless. That word is thrown around way too liberally in this community. I won a game in beta yesterday playing random 2's, which i mainly credit to ISU-152. It was Minsk Pocket against 2 okw. We were able to completely surround them, but could not move in on the fuel point they camped all their trucks and infantry on. ISU and JT showed up almost at the whole time, even with what should have been a massive fuel advantage for allies. JT blew my Sherman up by shooting through the damned forest that shapes the map(shot/vision blocker). I never saw it, just my half health sherman suddenly blew up. The guy controlling the assault gun was very smart though. He never overextended and asked me to ensure his retreat path wasn't blocked by my vehicles. He retreated at the right time for repairs. He had good support along his line and took his time taking chunks out of the okw defenses. This guy was one of the few that I have seen use the ISU cautiously like this. Most of the time(even from high ranks) I see people use it like a tiger or panther would be used, which results in swift destruction.
I can't comment on his experience using it, but worthless is the wrong word.
