I'm not sure I have answers, but I'll post what I've been trying. I'm a Ret noob, I'm just at that stage where I'm trying to figure out what will work for next expansion. So far this seems to work, and I'm happy with the dps. My Ret pally is really undergeared and I've only been doing the test dummy's and normals.

2-stepper (which sounds like it's going out of style...)

Step 1

#showtooltip
/startattack
/castsequence reset=combat crusader strike,inquisition,hammer of the Righteous,judgment,crusader strike,templar's verdict,hammer of the Righteous,judgment
/cast exorcism

Step 2

#showtooltip
/cast avenging wrath
/cast hammer of wrath

I'm such a ret noob that I'm probably missing something... I just use Icy-veins.com, Recount, Test dummy's and a couple runs in normal GB, HOO and VP. At the end of the runs, I check the DPS, check the breakdown of the spells used, looks like everything is getting fired off. I'll admit my use of inquisition is probably wrong (fires after 1 holy), for AoE it's the same but Divine Storm instead of Templar's Verdict instead. I run seal of righteousness the whole time.

Please provide any feed back (other then the obvious, 'You're a noob, that's all wrong' types of observations )
