“Interesting” is in the eye of the beholder, so that’s sort of a hard point to argue. We do think it’s more complex though. Part of the problem is it’s rather difficult for anyone to screw up the Ret rotation on live. If you hit things when they come off cooldown, you’ll do pretty competitive damage. You have no resource to worry about and it’s pretty hard to throw your rotation off for very long.

The change to Holy Power and adding spells like Inquisition and Zealotry means there is a lot more to juggle. If you let Inquisition fall or you aren’t prepared to maximize Zealotry uptime, then you aren’t playing to your full potential. If you don’t hit TV when you get 3 Holy Power, or if you religiously hit TV but eclipse buttons like Judgement in the meantime, then you’re not playing optimally.

Basically we are now engineering opportunities for players to make a mistake. If nobody can make a mistake, then there really is no test of skill and no opportunity for anyone to get better. That’s the “faceroll” rep that the tree sometimes gets saddled with — no matter what you do, you’ll end up doing high damage. In Cataclysm, that won’t be the case.

If you find you can master the new rotation trivially, then congratulations, you’ll be one of the better paladins out there. I am very confident however that not everyone will be able to do so, and so Ret paladins who do a lot of damage will get more respect for being good players than for having picked the right class on the character select screen.
