I also can't agree because the 50% proc combo is what makes MCH so unique. MCH was way too OP in 3.0, and sure it's nerfed the heck out of now, but I think the combo's fine. Most complaints are that the Overheat mechanic is not engaging enough or has any purpose to even bother with the mechanic. I did the math and overheating can't really be utilized at all so it's kind of just in the way.
