When discussing large balance patches like the one that's coming up, people hyperfixate on their class or classes of choice, and how powerful or weak they will become. The problem is that every class is seeing massive changes, and I'm not sure that any one person can have a complete grasp of every individual change.
Before we start griping about our nerfs, remember that everyone is getting nerfed. We need to play this balance patch and see how it all shakes out before we can start drawing conclusions. I could be wrong on my predictions for engineer. You could be wrong on your predictions for your class. But we need to see the changes first to know.
The hope is that they actually do follow up on their stated intention of balancing on a much faster cadence. Large balance patches like this need to be followed up with several small balance patches, to reduce the wild changes in metas that we've suffered over the last few years. If they can have a faster turnaround for balance, we'll all be better off.
