personally I removed this skill, as I found it didn't really benefit at bosses where the damage is huge, with it being close to maxed I was still taking damage on an aoe hit. Even worse is when the boss calls adds, that 300 or so damage shield isn't going to save your ass

A better option to use I found is calm, which works pretty good even at level 1, albeit with armour bonuses.
On the leveling front, to me anyway, not worth the energy costs and casting time to be gone after one or two hits from a mob, this is dual devicing (warrior) and solo playing.
Atm I'm trying bless, I'm feeling a little better about this skill. The energy costs are a lot less, and with the chance to completely avoid skill hits makes this an almost winner in my book. At 30/35, I am starting to see the real benefits now. It would be even better as a group buff.
The only draw back is at lower levels it's almost useless, with no discernable benefits.
