Why are Criterion dungeons so hard?

I think they kinda overshot the mark with Criterion.
Because the difficulty goes Normal (SS) -> Savage (ASS) -> The same exact Savage, mechanics-wise, with bigger numbers, global Enrage and you you also can't die (ASS(S).
I tried it several times with friends (and none of us do Savage) and we pretty much agreed to wait until 6.3 to get Augmented crafted and new Alliance raid gear to get at least 620 before trying again.
