Are you taking orders? How about Multiclassing, Custom Party Creation with increase to 5/6 members, subclasses: Arcane Archer, Storm Sorcerer. Looking up to you hopefully.

But those will be in the game when it launches

At least multiclassing will. Party of 6 already exists as a mod. And the subclasses I could take a look at if they are interesting, but not until sometime after the game releases because I wanna play the game as is intended and enjoy it first.
