Adding my two cents here that I feel the same, and I've been doing a rather large part of my EXDRs on MCH since it's currently my best ilvl job.
The only recent time where I've seen a wipe was when a tank decided to pull excessively with a SCH who I could wasn't too comfortable with the role given their gear (they were using a PvP book >>; .... ) and how they handled themselves. I was going to make it known to the tank to bugger off if they made a scene after the wipe but they thankfully remained silent and decided to pull less on the follow up.
