So I'm playing a campaign with this DM that LOVES to throw daemons and devils along with magic users galore at us, even though at the moment we are level 1 he tends to do things like send us against a Yeth Hound and between 20-30 goblins. Anyways I have this idea for a cross class should my Gunslinger ever die that is 2-3 levels in a Paladin (mainly to get the saves, immunity, and smite) then take the rest in Super Genius Witch Hunter class.
The problems I'm seeing is that:
1. Smite is Charisma based and most of the WH skills are Wisdom
2. The lose of potential WH feats due to the cross over
3. The actual usefulness of this class over all
