It’s a terrible decision, because BGs will again be full of M+ folks. There is no way they can make PvP gear relevant enough without enticing PvErs for farm it. So it’ll be average at best.
PvP stats were a solution that made sure PvP gear was BiS for PvP, and people could skip PvE aspects entirely if they wanted. Without it, PvE will always be a better way to gear up, which is annoying.
If they don’t want to have PvP stats, they should re-implement templates from Legion again, so that at least PvP outcomes are not decided based on how hard people PvE.
