I hate their system. Everyone is running everywhere in every surfaces... It's a mess when you have to place your companions with the chain mecanics... You separate, then you group again... One, or two, or more characters... The leader is changing everytime,.......
Anyway everything was said in the topic.
Larian's way of doing this is bad. It was in DoS and it definitely is in BG3.
Takes forever to regroup, even the first time Sven showed the game, he had problems with it.
