Okay, to be fair I genuinely asked my players this exact question after my last session where they teamed up with the “Totally Not Helldiver Vampires” and got a response that they all knew these guys are sus. They just want to wait for the inevitable betrayal first.

Its a system that does some things really well and some things very poorly, like every other TTRPG. Thus trying to force 5e to do things it was never meant to often either results in a bad experience overall, or basically not using the 5e rules at all.
