This is cute :)
But there is no need for the tank to be at full hp, they have large hp pools, they can get hit and drop a little.
Once you work out how hard they get hit, its more efficient to use the time it takes for them to go from a safe HP value to 'not so safe' to dps which as a SCH can be ages thanks to fairys. The shorter the fight, the less healing etc is generally required.
I understand stoning the other party members in the absence of a WHM, but you would be better off adloing as a SCH, and keeping stone skin up on the tank (excl levi) is extremely inefficient.
Sorry if I come of harsh, my internet tone sucks.
