Mobility may as well be renamed Hunter dodge ability. It can be totally ignored by Warlocks and Titans. Yes, mobility increases the height of your initial jump, but this is irrelevant to Titans and Warlocks since they get the most height from double tapping the jump button. The height of their initial jump has no effect. Warlocks/Titans: Ignore Mob, build into res and rec get class ability free. Hunters: Build into class ability [i]at the cost of [/i]res and rec. I think mob should affect sprint speed. That way each class could build into their class's ability and gain the benefit or build out of class and sacrifice ability. There is no reason right now for Warlock/Titan to take mobility, so they can put all their stats into the only two stats that matter.
