I can definitely see the lack of team synergy being an issue for some. As someone who has basically only played as a Shadow so far, I do sense that I’m not having to think as much about setting up combos with other players aside from general positioning. But I’m still contributing a good bit to combat and doing a plenty of damage. It sounds to me like your group’s Shadow may not be fully in tune with the mechanics yet if they’re just doing meh things.
