For the 12/8 paladin/fighter you didn't take Divine Might, which is itself much of the value of the paladin levels. You also didn't take keen edge, which puts you behind the 8-ball dps-wise since you don't have enough pally levels for the holy sword spell. It looks like you're aiming for roughly the same build concept as my Kensei Warpriest.

I have no opinion on the warlock build, having no experience with warlocks myself.


When posting multiple builds in a single post, you might prefer the "Code Tags" output format to keep things more organized.
