This question already has an answer here:
Part of the reason I'm asking this is because the UA centuar and minotaur both have a feature that says the type is both humanoid and monstrosity. This implies that having a non-humanoid race would not be balanced. But it seems that if the type was something like elemental it would be balanced due to the fact you could be bound using spells like planar binding and that this would offset the boost the spells such as hold person wouldn't work on you.
So would such a race be balanced?
