It doesn't make a tangible difference in most battles, but it does add up. It's more often crit from succor is where its at. You are almost always get a crit casting succor on the team somewhere.
It probably has to do with sch's crappy heal potency. Going higher in 2 mdmg(the highest teir stat mages can have) gave my sch all of.... 40hp in aqu power and maybe 15hp in succor... basically crap....might as well go crit in such a bad multiplier.
