Of course. I didn't want to say it's useless right away. In fact I think it can be very useful in a lot of situations when there is predictable incoming damage to a single player (or a small amout of players), assuming there are enough people standing in range.
My point was that it cannot be properly used as a a tank saving cooldown (aka "Oh S$!#"-button) like Guardian Spirit or Pain Suppression.
Its PVP implications seem far greater than its PVE usefulness, but it will no doubt be a "good" while not extremely potent tank healing cd.
