Cant speak for P8, But P5 with 3/8 members never doing savage, 1 of the tanks never having tanked before, was one of the most fun experiences i have had in a long time.

DPS check was extremely lenient, just required everyone to have a solid knowledge of mechanics and perform at a 'mediocre' level of skill to clear.

From what i have heard it's ridiculously hard for warrior and paladin to clear week 1 P8S without being hard carried by extremely good DPS (Currently 9% warrior and 3% paladin clears, with DRK 48%and GNB 40%), which is not a good sign when people are forced to swap jobs to clear.

Being week 1 its not that much of an issue, as times goes on people will outgear the DPS checks, but i can clearly see why it is disappointing for people that pushed the week 1 clears.

TLDR?
DPS checks were good early, it was all about fight knowledge and performing mechanics correctly. P8 is overtuned for week 1.
