All of the below have bugged/missing vibrations.
Mei - missing on endothermic blaster (freeze)
Moira - missing on biotic grasp (damage)
Reaper - vibrates only on every other shot
Zen - vibrates only on every other orb
Sym - missing on both alt and primary fire
Feel free to add anymore abilities or weapons that are missing their vibrations. Its really throwing me when im hitting someone as mei and moira but cant feel anything so it doesnt feel like im actually doing damage.
