This is especially prevalent for people who have the Asheara's set bonus that calls your followers to your side even when in multiplayer games. For example, if I had all of my follower gear on my barbarian, but my Demon Hunter has the asheara's set... if I switch to play my demon hunter I would have to switch every single followers gear to my demon hunters followers so that the followers could benefit from their gear because of the asheara's set, both in multiplayer and single player games.
