Warlock - the two friends who got me into Destiny had a titan and a hunter, respectively, so I did a warlock so we could compare them. This is early, nobody was above level 4 yet. I actually feel more confident now in difficult content as a defender with Saint 14, if level is equal, but I still main the warlock out of nostalgia or loyalty, so my warlock has the highest light of my three characters for now.
