Here is the rotation and spec I have come up with for my pally and tested it out on the ledges in Verlok Stand with no healer, which should be a good testing ground for any tanks. I rand laps picking up mobs and mowed them down, they did get me low on health a couple times, only cause for some reason the rotation hangs up after casting Holy Wrath in the sequence, but casts it again when it's off cooldown, usually happens when right when it fires off Avenger's Shield too, might be another glitch.

I use /click commands because Priority macros never seem to work for me like others have suggested or do. So, here's my setup, hope it helps y'all too as most run Prot pallys here with their teams anyway.

#1 Key
/cast [@mouseover] Avenger's Shield


#2 Key
/startattack
/castsequence reset=5 Judgment,Sacred Shield,Hammer of the Righteous,Holy Wrath,Consecration,Hammer of the Righteous
/cast Word of Glory
/click BT4Button5
/click BT4Button6
/click BT4Button12

#3 Key
/cast [@mouseover] Hammer of Wrath

My BT4Buttons:

5:
/cast Shield of the Righteous
/click BT4Button6
/click BT4Button12

6:
/cast Avenger's Shield (always hits current target first)
/click BT4Button12

With this you will not get the x5 stack from using Shield of the Righteous, but you will have a wave of constant self heals coming in from yourself and since WoG does not trigger the global cooldown for Prot pally now, with Divine Purpose, I have had this proc back to back and get me from 40% health to full in a second, that was from a bad pull btw. Still, try this out, it works really well so far for the spot I have tried, I imagine you will have no problems from it. IF it does cast Avenger's Shield and Holy Wrath back to back, chances are it is what triggers that glitch and causes it to hang up on HW while it and AS are both on cooldown. If it happens, I doubt you will loss any threat from the few second downtime on till it fires off again. Good luck
