Team-based initiative is legal according to the rules. Initiative by character makes perfect sense in the tabletop game because each player controls one character. Here, there's 1 player controlling all the characters.
I believe the idea is to make coordination with party members easier because you can split up your actions and movement based on what another party member does. However, I think it's at least worthwhile to explore the concept of individual initiative in the Early Access.
As long as it does not impair Assassins, fine.
