Confirmed: Sigma nerf/Sombra buff on PTR
General Discussion
Apparently hack cancels Sigma barrier on the PTR, but its not part of the patchnotes and could just as well be a bug.
That would be a change which would make sense in a sense to “fix” the double barrier meta, but i dont like it as it just adds another tank Sombra is very good against which enforces the Orisa pick further and doesnt make Sombra overall better.
Sigma players will complain and Sombra players only profit from this if the enemy runs Sigma.
Edit: Actually now confirmed to be intentional.
