I would like to see for Whm: Reraise like others have suggested, Sacred Prism from 1.0 (good for getting stoneskin, cure 2, whatever spells on everyone) and Rebirth from 1.0 as well. Rebirth was a spell that brought someone back to full hp and without sickness I think. I don't expect it to act the same. Maybe a 5min cd or something.

For Sch: Reflect/Shell, Dispel and possibly Aura. Reflect or Shell I see more like Succor or Adloquium that can put a magic barrier that can reflect a portion of damage back to the caster. Dispel speaks for itself. Aura possibly something that can increase spell speed, magic power, attack power and skill speed for 10-15 seconds or something. 5 min cd.

I'm not for sure that they would have to be exactly that and everything determines on cool down and cast time, but those are what I'd like to see.
