Gear based game. The reason why people play WoW is to get Powerful gear and own up PvP. If gear doesn’t matter no reason to play the game and it’s not an RPG anymore.
Balancing the fun right out of the game gets us nowhere and leaves us with a game that is boring and not worth playing. Take Legion Templates for example. Everyone hated Templates because it removed the RPG aspects of the game. The Devs said they were a mistake and they were removed.
The most important thing in this game is the RPG aspects, power from gear and Class fantasy. This leads to the most fun and why people are PvPing.
Most PvPers rather they remove Arena then try to balance for it by removing RPG aspects/gear. The only big mistake they made with PvP in WoW was trying Esports.
