Because it is bad no matter what these PvP players tell you. There’s a reason they’ve tried bringing back PvP set bonuses so PvE trinkets would stop ruining PvP gear paths, yet when the shoe is on the other foot they just gloat about how fair the system is.
It’s a garbage nostalgia swipe to WoTLK just like WoD was a nostalgia swipe as well.
When people get fed up with all the quality of life changes they rolled back, maybe by the end of this xpac we’ll stop doing WoTLK throwbacks and look forward in design instead of trying to make another crappy Classic throwback that nobody who’s playing retail wants to play.
