Maybe there is just no desire from Blizz to make the game balanced for all or at least most of the builds. I was reading the forum at the season start and it was all about the new meta builds. When playing, you check the builds around you and they are almost all meta. Maybe most players just want to be able to fart (I liked the expression) and kill everything around them. Makes them feel powerful. They just need in addition to that a game content where they can push their builds to their limit. They have the Pit for that.
The numbers are meaningless. They are limitless. See how aroused some players become when their fav streamer do billion damage hits in the PTR.
