That’s the point though, they didn’t really remove any of this. They just reduced the durations, and added damage on top of it.
Previously she used to be stealthy, but she had so little damage. She was still annnoying because of the silencing that lasted 5 seconds.
Now she is stealthy, has escape, can silence and has a relatively high burst damage.
Best thing for sombra is to make the damage bad again and replace the silencing with a better utility. A good starting point is her first version after the translocator rework, which can be tweaked in a better direction.
