My cleric's rotation changed by one spell. I didn't see enough of a change in my specific spec to really change anything I was already doing. Besides, no other game stays the same when an expansion comes out. The same rotation that you used at 85 in Cata is likely not the same rotation that you'll use at 90 in MoP. To piss and cry because you can't test out a possible new rotation is crazy. Let's face it, you obviously don't raid anyway, so you'll just grab your information off of theorycrafter sites about a month after SL comes out. Just like everyone else.
