Emphasis on the "little" bit helps... I don't know what the conversion is but it's low iirc... I would put it all in to Dex get your self a nice weapon with a nice proc and fly through levels...For leveling fresh, I'd go stam all the way. End game it won't matter like Manstomper said. But, those little bit of extra hp will be really nice til you get there.
But that's advice from someone that hates paladins (no reason I just don't like them).
And let everyone especially nazlum that someone has finally agreed with me!!!
