Its odd, I enjoy my Protection Paladin, but I absolutely cannot stand playing a DK for that very reason. Way too many abilities and rune cooldowns that end up feeling like you are playing whack-a-mole. I for one do not want to have constant procs that pop up completely changing my rotation every time I turn around.

And yet I also enjoy my elemental shaman, which is exactly that. Spam lightning bolt until lava burst comes off cooldown, and toss in an earth shock whenever fulmination has finished filling it up.

I think thats the difference that makes me enjoy the shaman while hating the DK. Shamans have a spammable attack. DK tries to merge a rotation (use this rune, then that rune, then this two run attack, hit this ability, then your first runes should have regenerated, repeat) with too many randomish proc's.

If you're going to have a proc based priority system, don't combine it with an old fashioned rotation. If you're going to have an old fashioned rotation, keep the procs to a minimum.

So far my favorite playstyle is my combat rogue. She has a nice steady rhythm in her rotation, spiced up a bit by juggling the different timers, with just enough spice thrown in with Bandit's Guile and Killing Spree that I don't get bored. The rotation is kind of like the base beat in some good house/techno. Its always there, pulsing in the background, with the timers adding some melody in a layer on top of that, and killing spree/bandit's guilde/adrenaline rush filling in the sudden bursts of excitement.
