No.So isn't that kinda... overpowered?
You have mismatched your expectations of what the terms used to identify varying encounter difficulties mean to the way in which D&D 5th edition actually uses them, or at the very least have looked at how the sleep spell performs in its best possible circumstance for usage, and missed that if that same XP value of encounter were instead with a singular monster that sleep would, on average, not do anything.Or have I got something wrong?
On average you can make 4 average hit point kobolds fall asleep - or less than a single average hit point bugbear, or just one average hit point orc because a remainder of 7.5 affected HP doesn't mean diddly if there isn't another creature nearby with that few hp.
