I find asylum extremely useful. Run Ravanna extreme with a few melee DPS, you can keep them healed and in case they hit his shield you can focus on blessing their slow debuff of focus on healing the tank. Let alone you can also drop it with a regen and go cleric to help out with the DPS checks. Another example I find it useful is on Bismarck's back, it allows you to heal the DoT before the next one hits with out having to use MP to heal. Remeber the new abilities other then Tetra are useful for the time you just don't want to spend MP or stay in Cleric for a minute like a scholar to help DPS.
