Warlock feels slow. Long thruster pack... annoying to me. Too much of a wizard feel. Not quite the ultimate Guardian to me. Yet, Hunter seemed weaker with a much faster pace. My style is Titan. Well balanced. If they would have made stealth more important in the hunter's abilities like a powerful melee or special assassination then I'd be Hunter all the way. But no matter how sneaky you are as a Hunter when applying a stealth attack it merits nothing. Trying to pick enemies off one by one without alerting the crew is impossible... at least in the beta. As it stands, Titan is my logical pick. A well balanced Fire Team would have one of each. Drawing from each others strengths and abilities. All one faction is powerful in only one area. Variety is the goal.
