Give her back a minimum distance for her DM to work.
A major reason why tanky comps don’t work right now for pros is that they have no good way to initiate. Dive can kite them forever. The initiator used to be Roadhog, but due to D.Va’s buff, the only viable target for Hog is D.Va herself. With this change D.Va wouldn’t be able to stop him, and tanky comps would be more viable.
Additionally, Ana would be able to self heal, and Zarya/Mei would be able to safely ult against by throwing their projectiles straight down. All heroes I think I’d like to see be made a bit less suppressed by D.Va.
