I originally chose the Titan thinking it would be a tank taking substantial damage for your team. I figured the warlock would have a support role relying on powers while the hunter would snipe. I like heavy weapons and shotguns with auto rifles and figured I could survive up close engagements with risk reward weapons like shotguns. Then reality set in where I was getting cut down before my buddy who was wearing a robe and had to stay back and hide a lot in order to survive. I never felt like the tank I envisioned originally but this was all way back at launch and since then I am just used to the play style I had to accommodate in order to play efficiently.
