Raise Diablo Hell Treasure Class to 87

Hello,

I am suggesting to raise Diablo Hell Treasure Class to 87.
I always thought it was a flaw that after clearing CS the Endboss of Act 4 Hell, which already has a monster level of 94,
only has a TC of 84. I think it would be fair.

*** For those who are not familiar with this fact: Diablo cannot drop items like Griffons or CoA like Nihlathak or Baal.
*** It would not destroy the good balance of the game, because TC87 with good droprate of uniques already farmable in 10 seconds (-> Nihlathak)

Greetings
