the 5-7% buff for each tank would in essence make the astro a required healer for certain encounters. Would not really make the cut. Turning one of our cooldowns into a buff that lets us stance dance temporarily in combat would fix all issues but ben 2 buff and shuffle pulling same card twice. Other then that we are practically on par with white mage for healing and stance dancing noc would allow us for emergency healing from a instant cast 500 potency heal+shield.
