If I'm solo (pretty darn rare, I'm level 58 now) I grind on monsters I can 1 shot. Right now that's anything under ujigi's w/ trial cross.
So: target monster, trial cross, dead monster, target second monster, overheal, hit with rod, target third monster, trial cross, etc. The main prob is overheal takes longer to cast. It's not horribly slow to grind like this.
Overhealing is underrated. I do almost 3k absolute damage to just about anything around my level. Sure, trial cross does more to the lower-level monsters, like almost 9k to a manyang
