Hanzo with scatter: Drops down and deletes someone by simply pressing E. No counter available.
Moira throwing orb out: Tickles away damage slowly and moves unpredictably around. Can be removed entirely by D.Va’s matrix. Limited use as it floats away. Target needs to be in a corridor or at low health for the orb to have an effect.
Yes. Scatter and Moira’s orb is exactly the same.
