Another point to take in mind in the case of AoE protections.

- DRK new skill Dark Missionary: Just 15% of magic protection, but only in magic attacks, 90 secs of CD
- PLD Divine Vail: 10% of your max HP, depends on a heal to proc and heals can undo too. 120sec CD
- PLD Passage of Arms: 15% of protection, ends if PLD moves, PLD cannot dps, 120secs of CD
- WAR Shake it Off: 8% of protection, can be incrised using others skills (the same skills we be lots if uses it), 90 secs of CD

I think its well balanced, since the majorities of AoE Buster are magic.
