Yea, Sombra has always had low mid fight but the strongest ult in the game. But over the years, because Sombra isn’t played in Ranked, they did buffs to her damage. You still can’t feel it in Ranked because even in T500 the cooperation isn’t all there, but now in OWL and pro league, Sombra dominates.
The dev’s should know that Sombra is fine, just you can’t play her in Ranked to 100%
