I agree, hybrids are essentially your "classes."
If you want a "paladin", you would want man-at-arms
+ bless, fortify (geo)
+ water of life (hydro)
If you want an "assassin", you would want scoundrel
+ desecration (witchcraft)
+ invisibility (aero)
If you want a "ranger" with pets, you would want marksmanship
+ spider, wolf (geo)
+ rain (hydro)
