I’m all for no changes but social dynamics have already changed. Any member of your faction can know your general location which is a major advantage in pvp.
You can track their raid progress and narrow their location down to gank them.
Admittedly this would probably benefit streamers the most. But in time this mechanic will be abused more once people catch on.
Awhile ago I was leveling on a server and was ganked in tanaris by a horde druid 20 levels higher than me. While my main was flying, naturally I checked my horde side… Saw his location change to thousand needles->feralas->Desolace. Obviously he was doing Mauradon. I showed up with my main and camped him and his group a few times.
Satisfying at the time, obviously this is an abusing mechanic and anyone can use it. An anonymous feature, hiding your general location, would solve most of dirty behavior going on today. Especially when world bosses become a thing.
