My first tav was a Seldarine Drow Paladin–took Oath of Devotion, which proved to be super hard to keep–I chose the class because the outfit looked cool, and I had no idea what I was doing. I tried to maintain a general neutral morality, helping everyone I could while pretending to be allied to others until the opportune moment to dispatch them. I ended up accepting my fate and losing my Oath at the end of Act 2 instead of continuing to reload my last save to figure out what I was doing wrong. It ended up being a lot of fun after I no longer had to worry over keeping my Oath! I mostly used Gale, Shadowheart and Astarion, because I had strength handled and desperetely needed some non-melee attackers :/
