Despite having played casually off and on for 20+ years, I've never played a paladin and would expect that I will be terrible. After a few years away I find myself on the road constantly and need a hobby that isn't 80 proof. I'd like to focus more on immersive roleplay and have a feeling I could make either shield or champion work. Any advice on either? Must do's, really bad match-ups to avoid (no that it will help, I'm sure), skills to rely on in PvP or PvE from either build, anything else? Thanks so much in advance!
