For me party limitation is just shouting "you are playing the game! it has game limitations!" And yes, nearly every game has such limitations... but they usually just dont make accent on it. You just know you have slots to fill and thats it (that is why I like system where you must choose companiaons each time and dont listen them complaning about being kicked from pre-made group)
In BG3 game is just throwing the fact that there are in-game limitations in my face. I meet Lae'zel who is eager to remove tadpole and when I ack her to join me she just says "no, your group is full (!), I`ll sit in your camp and wait.." what? WHAT???
The worse is with "new" camp system where the camp is build into the surroundings in dungeons... I like the idea, I hate loosers among companions being there. I travel through the dangerour area with alot of enemies (lets say Underdark) with 4 people, but each time I camp there are 6 people... What other 2 are doing I want to ask, follow at the safe distance or what?
Also found that each time I play I end up with the same "useless" compations sitting an the camp 100% of the time and doing nothing and I run with the same group of 3 and listen the same their dialogs that I already have heard many times... And I have feeling the same will be after release for me: one and the same party from start to the end...
