I’m almost certain Team 4, the Overwatch development team at Blizzard has completely abandoned the game.
It makes absolutely no sense for the sensitivity settings to still be broken after two weeks. This is supposed to be a competitive FPS game, a bug like this should have been fixed almost immediately via update rollback or pay your devs overtime. As of lately it has been disappointment after disappointment with this company. Letting a bug like this go by for so long then question why your competitive league is dying is just another level of incompetence.
