A little off topic but /RDM does get access to Raise. SCH is the better subjob but for me it's always been a little confusing with all the different job abilities and because no one I know is really doing VW yet because of how sucky the outcome is. I normally stick to /RDM in Abyssea. With 20 MP per tick refresh I rarely run out of MP and when I do have an oh shit moment, just convert and burn through another 2k of MP if needed (rarely is). /RDM is simpler for me, I would say?

/RDM seems like the best sub for a BLM to me though, with bonus MAB IIRC, Fast Cast, Convert, more Refresh, Haste and Cure IV that WHM once kept now we get with /RDM @99 so I stick with /RDM but I don't know the full benefits of SCH either.
