There will be a large part of the community who will not be happy with 8.0, 14's community is too varied in what we like for it to be the case.

In my case I care most about if a Job is fun to play, think WOW does it very well (When I played retribution paladin the class feel felt like I was permanently in FFXIV's paladin burst window). I really dislike this planning around a 2 minute meta, repeat x rotation y times until 2 minutes then do z.
I wish they would burn it to the ground and just make job's much more free-form , if that makes past ultimate's trivial or harder I really couldn't care, I don't do them and its an absolute minority of the community that does. They dipped their toes into this with VPR and PCT and the jobs were well received.
Ultimate enjoyers would potentially be very upset if it trivialised the fight but really from my POV if 10 more years are planned, you cant let the last 10 weigh you down.
I know full well that this view of mine isnt shared, but its an example.

Only those with rose coloured glasses, lost in the "SE Can do no wrong" mindset wil be happy with 8.0
