About Drow, Drow on 5e are so powerful that having to roll with disadvantage in few occasions would't kill the viability of the race,.
In other settings I might agree with you but BG3 has no day/night cycle so a drow would have disadvantage on everything, 100% of the time that you are outside...which seems to be a pretty big portion of at least Act 1 from what we have seen so far.
