An entire group of 31s I was just with did the Hardmode up to the deathsinger. No 32. We are fine. Just 10 percent less damage than you 32s.
Edit: I get that 31s can't do the entire raid on their owns like a 32, I'm saying why decline one for not being 32. If they can't pull their own weight kick them. Some can some cant.

32 got off that horse and praise the sun
