And about that deliverance tanking....I'm really wondering if this is intended by SE or not.

I don't think it was particularly intended-- they're changing tank damage calculations in 3.1, which kind of hints that "all STR accs, tank stance off tanking" was not really intended.

Of course, just changing the calculations of damage (presumably to make it scale from VIT at least partially) doesn't mean SE intends to completely do away with the meta that has arisen.

While I'm here... On the subject of lustrate, to me it's more powerful now. I did some testing in FCoB when I was maining SCH and my WHM was equally geared and I found this to be true on a warrior tank:
Cure was only slightly behind lustrate
Cure Crit was more powerful than lustrate
Cure + DS was more powerful than lustrate
Cure II was more powerful than lustrate under all circumstances save for healing debuffs

Of course, Cures couldn't (and still can't) be spammed like the 1-second recast lustrate, but 600 potency actually brings lustrate a lot closer to cure II and, as others have pointed out, it can crit now. And it's useful on DPS.

It can still be viewed as a nerf if you look at it strictly from being able to heal through debuffs and cleric stance. But in terms of healing power, lustrate actually got a boost/buff.
