It's not autopilot. Rotations have to be "interesting" in a way you have to pay attention to one thing or another. They dont have to be "fun". Fun adds overcomplication, wich no rotation should be.
You aren't talking about rotations then--you are talking about priority lists. Rotations are like what DKs had last expac, where you literally did the same things, in the same order, every 10-20 seconds. Priority lists are what nearly every class/spec uses now.
And theres no way to get rid of a rotation within the characters. There ways to minimize them depending on external factors. Different bosses make you have different rotations. But you will still have rotations to maximize your effectiveness.
A single random element to a class destroys rotations. That's really all it takes. If there's anything you only use when <x factor> occurs, and that factor isn't guaranteed by the rotation itself, then you now use a priority list.
Moonkins have several rotations right now, mostly due to eclipse. They are not getting rid of rotations. They are actually adding layers of rotations. You have your simple rotation Patchwerk-like wich is "boring". Then you have your rotation while you move, wich is plain stupid (Moonfire). Then you have your AoE rotation that is useless if you are not in Solar Eclipse and is utterly cumbersome to do in a fight like Heroic Halfus where the tank keeps moving from things on the ground and is really not good in a fight like Chogal where adds come from potentially diferent directions.
They wont get rid of rotations just because theres no way to do it unless every spell you have on your spellbook works the same way and have the same power, so it just wont matter what you cast.
This actually reads as a priority list overall, though it is possible that the priority list contains what are essentially small rotations (aka patterns) that you repeat in X circumstances. Still though, boomkins definitely don't use a rotation.
That's what we mean when we say auto-pilot. To use a rotation not only requires no skill, it doesn't even require you to look at your screen (assuming the boss isn't moving, of course). My DK for much of last expac was basically just 1, 2, 3, 3, 4, 5, 5, 4, 4, 4, 5, repeat (or something like that).
Literally, that would give me my top dps on a pathwerk style fight. The only possible complication comes from CD usage, but that wasn't really intense at all.
That's not the case with boomkins and hasn't been since they first introduced eclipse. Believe me, you'd definitely notice a big increase in boredom if you played a rotation-based class after being used to Druid.
