>As fervent crusaders in their chosen cause, paladins must choose a deity. Paladins choose a specific faith to serve, as well as an lignment. You must choose an alignment identical to the alignment of your patron deity; a paladin of a good deity must be good, a paladin of a lawful good deity must be lawful good, and a paladin of an unaligned deity must be unaligned. Evil and chaotic evil paladins do exist in the world, but they are almost always villains, not player characters.Paladins are not granted their powers directly by their deity, but instead through various rites performed when they first become paladins. Most of these rites involve days of prayer, vigils, tests and trials, and ritual purification followed by a knighting ceremony, but each faith has its own methods. This ceremony of investiture gives a paladin the ability to wield divine powers. Once initiated, the paladin is a paladin forevermore. How justly, honorably, or compassionately the paladin wields those powers from that day forward is up to him, and paladins who stray too far from the tenets of their faith are punished by other members of the faithful.
I like this so much more, than 3.x Paladins, yes, maybe it's not "canon", but it gives you idea how you can became one, and instead of "lol you fall" you can become an outcast, even being hunted by your own sworn brothers, so many possibilities for RP and storylines and you can do what you want, chose your own way in serving your god without being tossed around with stupid mechanic.
And if you have stick up your ass so deep, you always can play Sacrifice paladins.
