If you notice at 8:48 in the reveal/with commentary vid that the Titan double jumps as well. It has been seen talked about numerous times that the Hunter double jumps and the Warlock glides, as perhaps an"standard" ability. Now, seeing the Titan double jump, I wonder is the double jump and glide are abilities(standard or not) that are not so much dedicated to a specific class, but can be chosen or changed as you decide how to play your guardian. Thoughts?
