I think clear in-game cues would be enough, IF the game is designed well for no DBM-type mods. If they want to design encounters that are SO difficult and complex that things like DMB are necessary (but not include in-game cues), then they should allow it. One thing to remember about DMB is this: It might tell you that a boss is about to shoot fire at your face, but it can't make you skilled enough to successfully dodge said fire, while still doing your job.
