The difference between Paladin having a raise in battle and a summoner having raise is that a Paladin can get hit by a truck and live; a summoner cannot (No defensive CDs even). Most classes share a bum skill. (RUIN) White mages get 3 good cross class and share very good cross class. Stoneskin (maybe protect over mercy sometimes) + MRD cross is all PLD needs. If Paladin does need more utility they shouldn't be looking at cross class to improve themselves.
