Larian was able to get away with this in DOS because they did not use a fixed, class based system. (Yes, I know Gale can learn healing spells right now, but that needs to be addressed as well). For example, if I want to play a Warlock, it is rather difficult to bring Wyll or Gale with me without handicapping my party's capabilities.

In a system with a maximum party size of 4, and all characters using a class based system, it is extremely difficult to cover all of these needs and still have room to bring along a party member you're fond of who already has their class-based role filled. A utility character who can accomplish tasks like opening locks, disarming traps and generally being rather sneaky. A magic user who can provide access to mystical tools. A tank of some sort who can help protect the squishier folks and dish out some damage. A healer who can keep the party on it's feet. To be successful, the party will generally require the following things: In BG3, you have a party of characters who must work together to achieve their shared goal(s). And I firmly believe the reason has to do entirely with Divinity: Original Sin.

I've now got about 30 hours in the game, and the number one issue I have is that the party size is too small, by at least one character.
