I suggested this idea many years ago, no one listened to me.
I keep making suggestions and have a lot of ideas for WoW but every time I do, my ideas are either shot down vehemently by the forum regulars or Blizzard doesn’t do anything until the situation becomes dire and they lose masses of players.
At this point, if Blizzard wants ideas to improve their game, they can at least start hiring and actually paying people for their time and effort.
