Divine Spells compared to Arcane Spells sucks.
Divine Spells compared to no spells is Amazing!
Having a half dozen buffs, each capable of making the fighter cry, applied to you 24/7 is great too.
Ray Deflection + Stormlord(or w/e) = immune to ranged attacks & flight & free ranged blasting = Blow shit up while invincible.
Divine Power > Fighter
Necromantic Empowerment + Visage Of The Deity + Bite Of The Whatever = Powerthirst!
Raising and commanding your own army without the -everyone-can-take-Leadership-feat is great too.
Did I mention you can still call favors from interplanar creatures too?
Being able to use Anyspell to cast almost any Arcane Spell is amazing.
Arcane Fusion anyone?
Being a better caster while being a better meleer than the classes that gave up some spells for melee (paladin/ranger) is great too.
Srsly, Fist of Razial in every possible way replaces the Paladin. 10 levels and it has more smites, better smites at that, and still full casting.
Let's not even go into how well the cleric out performs classes like the monk or fighter or the whole cast of wannabes like the hexblade, duskblade, spelltheif, samurai, ninja, warlock, shamen, marshal, healer, etc.
