It is the easiest DD by far, I've soloed all of them and this one was done first try without complications. I feel like they tried to balance the DD for all jobs to perform equally.
Palace and Heaven very much favored tanks, the high auto damage is a lot to deal with for anyone who isn't a tank, or playing a job that can't kite mobs.
Eureka Orthos felt like a response to that and flipped the script, High Autos were gone and everything was a mob with a mechanic that oneshot anyone including tanks. It was Pretty terrible for tanks and Healers due to the bloated HP values, Selfish DPS reigned king.
Pilgrim's Traverse feels like it tried to account for that too, so not only are the mobs HP significantly lower than EO, they kept the mechanic oneshots focus. Eureka Orthos was already considered easier than what came before it because once you get over the initial hurdle of learning all the mob's attack patterns the difficulty just flatlines around floor 70.
So Pilgrim's is Eureka Orthos with less health, no Amnesia and No Blindness. The mobs themselves have a lot less varied mechanics and do primarily line/cone aoes. This feels like a direct response to how hard Forked Tower flopped, I think they want non raid content to be easier for wider appeal.
