Giving the benefit of the doubt, there's still some issues.
WotC shouldnt be catering to Hardcore Gamers, at least not primarily or any more. They did this with their first few adventures (most of them in 5e being homages to classic adventures to appeal to long time fans).
There are wonderful TTPRGs out there catering to those of us who consider themselves hardcore gamers, but we need a giant casual flagship to draw in new people (oNE OF US ONE OF US) and WotC fills that role. I dont agree with everything they do, but I firmly believe we are all benefiting.
