Well I personally started out as a hunter, and they are a lot of fun in battle, but after a Titan, you will be super frustrated with both the jumps and the grenades. My main is now a warlock, I really love it. And though most people run sun singer, for the revives. May I suggest trying out void walker. It is a super fun class, and you can put out massive destruction. Some must have abilities are the axiom bolt grenade, and bloom. You must have bloom.
