This is in regard to the Paladin's special ability Aura of Faith -- Page 22. (And possibly by extension, Holy Champion.)
Paladins are Lawful Good. Not just Good. I have had issues with this for some time. If Paladins are just "Good" Warriors, then make them so that they have options for different levels or types of "good". If Paladins are Lawful Good Warriors, then have something that brings out both aspects of his alignment. Make it so that Paladins have (at least) the option of smiting chaos or make their weapons lawful aligned for the purposes of getting past damage reduction, etc.
Mostly just an opinion, but Paladins are not just "good".
