How do groups generally work in Bozja? Is there specific compositions like with regular duties, or is it basically a free for all? Do groups generally stay together, or is it some kind of split farming deal?

It's like I said, I plan to be disappearing a lot and playing erratically because I'm at work. I'm fine with doing the group thing for the occasional boss fight, but don't want to have to be keeping pace with a group the entire time I'm in Bozja.
