As I said in the last post on the previous page, the only difference is that the M36's turret speed is 24, compared to the M10's 60.
So the M36 is actually just a (very slightly) nerfed M10, and the misfire is still present.
I agree with Oddball. If its going to stay around, I don't think it should be a full replacement, but a reward unit. I don't really feel its a big deal that the US would have 3.
