If you're using a balor who's not a demon or who associates with devils, then you're already not using a D&D balor, or else something else is wrong with the picture (the devils are charmed/dominated/geased?). That's an assumption that most players who know what a balor is would make, and that's a pretty fair assumption.But, Mirtek, what if I actually want to use a baler?
4E's reception and subsequent demise and the resurgence of previous-edition lore in 5E is proof that D&D needs D&D tropes and flavor. It may not be the case for every campaign, but I'm sure WotC didn't just decide to completely revert such a huge 4E premise without solid market research.
