I think that’s the issue. People thought that patch will make more builds reach lvls of HDin, Blizz/light sorc, java and so on. Patch was aimed at making more builds viable, and viable doesn’t mean annihilating P8 games in seconds. Personally if every build was able to do that, this game would got boring for me pretty fast.
Frankly not a single build should be balanced around its P8 performance, all builds should be balanced around P1, and if any build over perform in higher player setting, it should be nerfed and not become new balance point for other builds.
