SE: if it aint broke, dont fix it (War)

I don't think I would bother switching back to Defiance unless I REALLY need to, since Unchained only lasts for 20 seconds, and even then I would be missing out on 5% damage dealt.

Not to mention I'd also be missing on Deliverance's crit increase.

Some quick napkin math and it looks like it would be worth it to switch into deliverance (tank stance) for unchained and upheaval. Especially if the rumors about unchained double dipping on upheaval are true.

The bigger issue in my mind with this is that this would effectively mean Warrior would have 0 penalty for using a nonzero amount of tank stance, which is a huge benefit to have, essentially another 2 minute cooldown.

20 seconds is more than enough(twice as much actually) time to go back to Deliverance before the penalty kicks back in. I never suggested to sit full time in Defiance, just enough to take advantage of Unchained and the increased Upheaval damage.
The loss of 5% bonus from Deliverance and the varying bonus crit would indeed be something to consider, but that might be outweighed by the gain in healer dps.
