So I've been playing some 4e and some 3.5 lately, and pretty much all the classes in 4e can be fairly easily mimicked with either a base class or a prestige class in 3.5. The avenger seems to be an exception to this, though; I can't find any support for a lightly-armored Paladin-type character, divinely empowered but quick rather than strong. I know this is the min-max board, but I'm not even looking for something extremely powerful, just a way to make this concept playable in a campaign starting at very low levels and running into at least the low 10s.
