How hard is Ultima HM compared to other endgame content?

[Doo]

hard to believe because the dps check is pretty unforgiving. You have 10 minutes to kill it or you die and even with amazing dps, you'll only have about 2-3 minutes to spare

I have beaten it like 30 times in DF (with players that said they were new), you're not going to get that type of odds in Garuda Ex. It's mostly a healer check rather so I queue up as whm.
