I suppose I've commented on this before, but in case I haven't, I'll do it now. History obviously has its place in all of our hearts, but I just don't see adding a GV to the game that will just get pwned by anything but an M8 for history's sake. If it were a pershing or something else that could stand up 1 on 1 with the german armor, I'd be fine with it. But the simple fact that the American advantage of simply producing more tanks than the Germans does not apply to the gameplay we see here, so it is mostly irrelevant and makes for lopsided fights.
Just my thoughts...
