I genuinely believe that good posts massively outweigh bad posts on this forum. Obviously there is some unrealistic moaning but it's a tiny fraction.
I also don't think Extended is in a particularly bad way, looking through List Fortress for eg, there is still a much greater variety of things being used, and used well, than at the tail end of 1.0. Low key adjustments could go a long way.
People need to be a bit more positive and a bit more aware of their own confirmation bias. Otherwise it really doesn't matter what they change.
