Garrison is the primary exotic used for titans, so a majority will have more mobility. Blink has all but been erased from the game, the cooldown and detriment to recovery have severly impacted it. Invisible, sure i guess, but with a sound effect that alerts everyone and it lasts only a short time and immediately disappears if you were to use blink. Using Blade's swipe to evade drastically reduces the super's availability, it runs out incredibly fast. As far as we know now, they haven't touched the other roaming supers. Saying that nerfing Blade to make sure it isn't OP while leaving Storm and Sunbreaker virtually untouched is unacceptable. The person in charge of these changes obviously has no clue what he's doing (evidenced by his ineptitude while playing crucible) and that fact that he has support from the community on the nerf to Blade is of no surprise.
