You're fast, but not agile. Double/triple jump makes you agile, blink makes you agile, shadestep makes you agile. Titans float in a straight line slightly faster then the other classes. A titan floats towards you, easy pick up. A hunter is double jumping(not even talking about blink) not an easy pick up. Twilight garisson is finally the evading skill the titans need, and it costs them a exotic armor spot. Btw, I main a warlock and a hunter, and i hate titans.
