I’m sure many would apprieciete ability to see what careers are already in the game before connecting. It would allow us to make a more informed decision when picking your own class. No one needs 3/4 ranged focused characters in a Legend difficulty game.
Would deff increase the ability to build a well rounded team. If you can see what they are lacking, you have the option to help balance the team (or go for 4/4 ranged, :P)
