Just got MCH to 70 this last weekend and by far one of the most fun (albeit sometimes extremely frustrating) jobs I've played. I never played, or even leveled it, during HW so I only have SB MCH for reference.

I can't seem to relate to these complaints, though. If you can actually execute the rotation on time everything falls perfectly in place. The annoying things are disconnects and mechanic type things going on in the fight, not really with MCH itself (imo). But eh..
