The biggest issue has always been that the hunts are insanely undertuned for the average player turn-out even before cross-server/world was introduced.
It got even worse in EW/DT as the S ranks only have around 50% more HP then the release extreme bosses do when it was closer to 200% in ShB. A DT S rank has around 88 million vs. Valigarmanda EX's 61 million, whereas ShB S ranks had 27 million vs. 9 million on Innocence EX.
