In my opinion the PvP stat template single handedly killed pvp in Legion. I've never seen pvp in a worse state or with lower participation than it is today. Making gear not matter in an mmo is very counterintuitive and removes any sense of meaningful progression. This is just another example of catering to bad players so they don't get completely crushed in random bgs. High level pvpers have amazing gear anyway so it doesn't help them. There are games with stat templates that work such as mobas, most shooters, pubg, etc but they don't have a place in mmo's.
