most of the players uses mule characters to increase item drop rate. But that requires lots of copy of diablo at the same time. That is not user friendly. Also cause burden to the server. because 10-15 characters loadded at the same time but only one of them are actually playing.

Adding a "add null player" and "remove null player" button may help to both players and server at the same time.

That null players are not actually there. they just act like they are there and increase difficulty and drop chances. but does not require another copy. dont have items. dont have action.

or maybe just an "increase difficulty level" button might work too. (pratically the same thing)

it saves lots of time for players.

thanks in advance.
