Nearly 50, would like a second Job, how viable is it stat wise?

you may also want to look at Cleric Stance, i think it is a cross class skill from Cnj, available to WHM and SCH

Not a terribly good fix, unfortunately. The general idea, I guess, would be to pour all your points into INT and then you'd activate the stance in SCH to heal rather than nuke, as it puts all your boosted INT to MND. Problem is, it's still gimping your Cures by 20%. It would work much better if you could use Stance as SMN, but, alas, you can't.
