The "nerf" to Fury barely made any difference at all in the vast majority of cases.
The logic is that if you have to nerf something you should nerf it a lot, so that you don't have to nerf it again, but maybe can buff it back up a little, later.
However, that same logic SHOULD have dictated that if you're going to buff something (Tankers), you should only buff it a little, and you can buff it more later. That part of the logic got forgotten, unfortunately.
