Really dig the ranged bubble mechanic. I had a feeling that would be the next thing we would see, just seems like the only thing missing from the current tank lineup we have. They also seem to want to give a similar mechanic as a base mechanic and an ult to characters of the same role. See infra-sight Widowmaker ult/Hanzo basic and power buff Ana ult/Mercy basic. Now they are doing that with the Zarya pull ult/Orisa basic.
