Definitely a Warlock for me! I love the look of their armor, those cloaks are bad ass and look like trench coats! Also to be a gun wielding mage will be awesome, the abilities look really powerful, and it seem like they will be able to do some buffs for allies which will be very useful to a team. I have to admit though that the Hunters look really awesome with the hooded capes, as well as some pretty awesome abilities. Most likely I will play as all three but definitely my main character will be a Warlock.
