Do they really need to have a "title" of their own? What if you can pick skills and feats/traits/whatever that can make your fighter do what a paladin does in traditional D&D?
I'm probably hoping for more character build customization options than a larger number of traditional classes.
I respectfully disagree good sir, give me fully fleshed out paladin and bard character classes, full of awesome bad guy smiting and musical buffing bells and whistles (respectively). The monk and cipher do absolutely nothing for me personally, but I know there are people out there looking forward to those classes, and I wouldnt take that away from them. My first ever BG character was a Paladin, who worshiped Helm...EVER VIGILANT!
