Hot take: The best movement [i]potential[/i] should require a build, not "Slap on exotic X and profit." Rework the movement exotics and make mobility effect sprint speed and slide distance in addition to its current affects. Maybe make it affect AE as well (if AE just has to stay). Players should have to really decide to between the top three stats. Right now Titans and Warlocks benefit from low mobility, which makes resilience and recovery no-brainers. Recovery does so much right now I'm not sure what they could do to make it matter more. A nice buff would be to make mods cost less though. The current costs are really outdated. That and armor affinity need to go.
