Why is mp recovery useless?

I'll be honest with you,training-wise.I don't see myself doing mp recovery + drain every now and then.I'd waste too much time while I could do other combos that would speed up my training. Oak barrel isn't that usefull but then again i'd rather have this than mp recovery.

Stay tuned for pirate control video #2. Guess I gotta show some mp recovery in there too. Trust me, it doesn't get in the way at all. You don't have to use drain right after mp recovery, but being able to heal the lost hp with drain is a big plus.
