I can't find the fun in this game any more

What differences do you think of? Because I can't think of any big changes in how combat works.

more negative changes
overall simplifying and 'dumbing down' of classes - everything feels same-y. great homogenization of classes, a big noted example is all the tanks feeling very similar
removal of major skills on classes, which strips their identity ( removal of noct sect as an example. i get Why they did it but just to give an example )
overall dungeon design is the same ( pull some mobs, kill a boss, pull more mobs, kill boss 2, kill more mobs, kill boss 3 ) with very little variation, and removing interactions" from dungeons ( example being you don't need to interact with items to open doors nearly as much - though personally that is fine since it makes the dungeon quicker, just an example of a change )

removal of healer's 2nd dot, personally a change my friends and i didn't like but i know some people did, so i'm putting it in the middle lol

more positive changes
overall fight design is better and fights are more engaging, even at normal ( aka not ex or sav ) level they are fun and feel unique
some jobs still do retain their unique traits, which does set them apart. not a Change but an example of a lack of change
pvp makes jobs feel more unique, which is good

a mix of good and bad, but i started in SB and the game plays pretty different compared to in SB. some good some bad but it for sure has changed.

Those two are really aspects of the same thing. Yeah, there has been streamlining and homogenization of classes/jobs.
Doesn't really change combat in general, only minor changes (major in a few cases) in exactly how each class is played.

That's not a change from HW to EW. Or a change to the game at all.
Dungeons have been samey the whole time from ARR onwards.
