I have 2 chars level 60, and if I want to solo with either of them and I wish to have a certain follower I have to start a game as my last played char, take the items off, put in stash, then start the game with other char then put them on to ensure my follower has the best gear it can have.
Why not, when your chars, and its respective followers on that account hit level 60, have the option to merge followers?
How it would work is, if you have a Monk level 60, and a Demon hunter level 60, and all 6 followers are level 60, all you need to do is strip the items completely off say, the Monk's followers, and then the game recognises a bare follower and the player gets the option to merge followers between them so no items are lost. Could alternative have the level 60 follower like the Crafters, account bound at level 60, but then there is an issue of items lost when they hit go from level 59 (not bound) to level 60 (bound), guess a tooltip can come up saying, "if you want to bind remove all items and click accept".
Obviously a char that is level 1, shouldnt be able to tap into the level 60 followers as it would just be silly, so it only is available at level 60.
This helps because when I play DH, if I find a good crossbow, if its good, but not quite as good as my own I'll see if its better than my followers, I'd never bother going to the trouble of finding 10 decent crossbows to give to all the possible Scoundrel followers on my account, I'd just swap it around.
Thoughts? It's really just a convieniance factor.
