Unfortunately, until encounter design changes from being "tee hee everything is Savage now" jobs will continue to be homogenized.

Double unfortunately, hardcore players will throw an ABSOLUTE FIT if you dare suggest that encounters become easier in any way so the scale can shift back to jobs being complex instead. They want jobs AND fights to be ball-busters, and will never accept one or the other being "brain dead" because how dare casuals be allowed anything. It's why you don't see many of them actually complaining about the current state of things, because it's "filtering as intended" for those they deem lesser, while they get to engorge themselves on content only they can beat.

And yet when job changes happen again right before the promised Ultimate drops, it'll be casual players being blamed for the changes despite how few of them are even still playing, go figure.
