I believe that some people have gotten so riled up by this change because that panel with all of it's "unnecessary" stats and info was part of a bygone age in the game's life and somewhat still held up a veneer of complexity that this game obviously does not have anymore. Maybe they saw the new changes are went Luke Skywalker on it, screaming Nooooooooo Noooo NOOOOOOOOOO after having heard Darth Blizzard tell them they're playing the equivalent of mobile facebook cowclickers. Or whatever this is:
However i agree. I too feel that having more stats displayed was misleading and clunky, i mean at times i had difficulties reading them (after seeing the sheer number of them) and breathing at the same time, or doing anything else really. This is a welcome change from Blizzard seeing as it removes a very possible health hazard from their game.
