Oh good, can't wait for the class to be destroyed. Nuanced changes are not something we often see.
Knowing how these things usually end up, we'll probably get something like:
Nerf MH pistol into the ground => Scourge back down to normal levels, Harb now unplayable unless it gets buffed at the same time.
OR
Nerf Scourge => Scourge baseline now balanced around MH pistol, scepter etc unusable.
Or, quite frankly, some other inexplicable change that will leave half the class unplayable for months. Of course people have already made some good suggestions on how to avoid things like that, I'm just not confident that will happen. 😟
