Good is Not Nice: A Paladin's Guide

[Nidgit]

There are a few subclasses that might be considered tricky or problematic based on what type of game you're playing, but that's due to Oath mechanics. Playing Devotion with its ban on lying in a intrigue-heavy game, for instance, will give you problems. Ancients and Redemption pretty much prohibit playing in an Evil or murder-happy party.

As far as actual combat abilities go, most paladins play pretty similarly. Charisma is definitely more important for a few of them, like Conquest, and some lean more towards offense or defense. But on the whole, you can pick any subclass for the flavor or one or two abilities in particular and not worry about making a bad choice. Every single Oath is good.
