Titan's best health with out the use of an exotic. Titan's heal on melee and on shoulder charge which is super easy to use. Titan's mave better speed than warlocks who are not utilising blink. Titan super is easiest to use and has greatest AoE. Titan has Lightning grenades which is basically 3-10 free kills per control match. Titan is by far the easiest class to use, however they seem hard to use because you can't resort to jut blink shotgunning. I play all three and titan is my favourite thanks to lightning grenades.
