Look guys. Aside from removing /follow (or instead of) they could just make it so damn annoying TO box that nobody wants to. Change the system, don't force people to change to adapt to it. That is all they would have to do. They are already doing some of it - even if it isn't intentional. Dynamic outdoor instances/quests that wreck /follow. Vehicles. DKs. Dungeon content that makes it impossible to progress with a single person at the helm, etc.

I see no compelling reason why Bliz would want to make boxers go away though. But I don't see any evidence they are encouraging boxing either.
