It's funny because there's clearly two groups of people: those who care about keeping job identity even if it means they don't like all jobs and those that are OK with homogenization of jobs since now they can "enjoy" all jobs.
I use enjoy in quotes because ultimately that leads to all jobs being essentially the same with different animations.
While I played since ARR launch, this expansion was the first time I took the time out to actually level all jobs. As I was doing so I'd often make comments like "wow this job feels a LOT like this other job...". Which was met with folks maining those jobs saying how it used to be different (in a good way).
For example: AST is just a better version of WHM. I used to main WHM but now I main AST.
Is this good design? NO. Just fix the aspects of WHM kit that feel bad or don't work well (ie: MAKE IT LIKE AST IS NOW) and make AST unique. PLD and GNB are super similar too, I main PLD and I "enjoyed" GNB because it felt familiar . . . not because it was its own unique thing. Is this good design? Again, no it's not.
The whole purpose of having different jobs should be to make unique enough play experiences that they stand out on their own and appeal to a certain type of player. Otherwise, why even bother having different jobs?
This "easy mode" they want to employee for making new jobs deflates any sense of excitement I have about future jobs. It makes the game feel creatively bankrupt and ultimately won't appear to those who have stuck with the game for so long.
It's extremely frustrating to watch happen and frankly *I don't care* if someone finds SAM entertaining *now* because it's a watered down version of what it was. If you can't find a SINGLE job you enjoy to make your way through the game then I'm sorry but this game isn't for you. If people want the bar of good job design to be "everyone has to enjoy all jobs because REASONS!" then enjoy your boring game but don't be surprised when it becomes like WoW, a soulless husk of its former self.
