How about this macro/rotation for Paladin off tanking?

It's a good idea, but I think it would end up being inefficient, and not from a mana standpoint.

The chances that your one stoneskin every 3-6 GCDs is going to be 100% effective without you timing it is pretty low. My general OT rotation is more like a BRD priority list than a rotation:

0 - Would it make sense to use cover? > Cover
1 - Is RoH on mob? > RoH
2 - Do I have less than 500 mana? > RB
3 - Is the MT in a high dmg phase? > SS MT
4 - Are healers/dps going to be taking dmg? > SS healers/DPS as I can
5 - Am I going to be taking damage? > SS myself
6 - Do I have full mana? > SSs on MT>Healers>DPS>me

I think its a good idea if you want to go on auto-pilot and add a little more utility to the group, but you will get more effective results from being cognizant of what's happening in the battle.

Well, I didn't mean to use it as a way to go into auto pilot and not pay attention to what's happening in the fight. I was thinking about it as more of a utility rotation to use when you're normally just spamming the RoH combo. Which I see way too much of with Paladin off tanks. Heck, part of the reason I can't rotate in SE when I'm warrior main tanking is because of Paladins staying in Shield oath and spamming RoH non stop.

....Paladins staying in Shield oath and spamming RoH non stop.

Yeah that's annoying as all hell.

I get what you are saying for sure, this is a nice bit of conventional wisdom for people who don't feel like min/maxing on their performance for PLD. I felt I couldn't let it float out there without the more involved strategy being toss in though, haha.

Edited out my other sentiment because I'm going to make it its own thread.
