Asian teams play with so much Sombra, it's pretty sick to see how they use her. Confident she's pretty underused in top level Western/Korean play compared to her potential; Meta Athena used her a bit but there are a load of cool things you can do.
Definitely. I'm on the boat that says Sombra is extremely powerful due to how insanely fast you can charge her ult, and I'm confident with the OPC starting that Sombra's popularity will rise a lot
