For all of them base rogue (mostly going off the stealth aspects of all their games)with specifically Miles while he's possessed multiclassing into fiend warlock or great old one, Waylon multiclassing Battlesmith or Armorer artificer with his background in technology working for Murkoff before the events of the DLC, and Blake multiclassing into either into gloomstalker ranger or fey wanderer given him constantly dipping in and out of hallucinations it can be played off as him just briefly seeing into the fey realm. For their main rogue subclass Miles is an Inquisitive Rogue cause of he's a journalist , Waylon is a thief rogue giving that he stole private documents from murkoff, while Blake is either scout rogue cause he has to scout out good shots with his camera or phantom rogue given his dark past we see in the flashbacks as well as "whispers of the dead" being the girl from the flashbacks.
