Dying often in Crucible because Titans are so stupid slow outside of their sprinting (and shoulder charging, but that doesn't really count) is just an awful experience, when I at the same time see Hunters use Stompees, Jumps and Dodges to change direction instantaneously and Warlocks having Blink and In-Air Dodge to move fast across the battlefield. I think an improved Slide on Striker would do pretty well. It is ground requiring, works especially good with sprint and fits the class identities.
