Also you are wrong about the effects not requiring high strength. the basic Divine Light wants 8 STR (30% penalty at 5 STR), and Lower resistances wants 10 STR (50% penalty at 5 STR), and that's just to get rid of the fumble penalty. Mages can't really afford 10 STR.
Yep, you're right. You could maybe dip one level into it but not much more.
