They base nerfs on overall data. Blade has had the highest k/d across all playlists for a very long time. Why? Id say more because of quickdraw which effects every single engagement vs. blink/super. Blink has been nerfed into the ground because it takes advantage of something we can't control which is vertical sensitivity. If we could modify that blink would be fine but seeing as how our sensitivity is locked it honestly shouldve been replaced until Destiny 2. No one uses it anymore and after this it would be completely illogical. Might as well just replace it now instead of nerfing it into the ground.
