Seriously?
Every other class gets a pretty effective evasion tool with this jump yet...not the Titan.
Not to mention if used effectively its a great tool for attacking an opponent. Ive had plenty of Warlocks and Hunters evade my shots and appear inches from me to use a shotgun blast or a melee to one shot me.

It doesnt make sense for the big guy who has nothing to do with magic to have blink.
