MCH is amazing ! The rotation make sense now, cooldowns are aligned nicely, and I can outdps my bard, not by a huge margin, but there's less rng involved so... I'm sure MCH dps is superior to BRD dps on average.
Dismantle is really good now, it's close to bard's utility, I love it !

I can understand why people prefered the 4.0 MCH, but I like this one better personally, so it's up to the player I think.
