I thought it was handy you could see the player list before logging on, since relogging is more than two quick clicks for me.
(Although if the lagg decrease and server stability is significantly impacted when enabling this features, I'd understand.)
But if this feature does ever return I sincerely hope it will be as before, where it doesn't show which class(es) everyone is.
Whether we can see if a DM is online or not doesn't matter much to me, a lot of the time they're already pre-occupied.
