Unless they do away with raid buffs, jobs that have burst profiles that align with the timing of the raid buff windows will just be prioritized over those that don't. People think they know what they want, but in the end always optimize the fun out of the games. Square has currently more or less prevented this by making every job align with the same timing for their burst. That's how it should be.
I think they should even do away with 90 second cooldowns, and I don't even think that's a hot take. It's annoying to manage bunshin on nin. Maybe if it didn't cost ninki, but since it's an awkward timing that also costs resources to execute, I really just end up disliking it and it puts me off maining the job even though nin is my favorite gameplay out of any mmo job/class ever made.
This thread has made it pretty clear that people's main "issue" with "homogenization" is that it all falls into the same timing, but that's literally what makes this game good and keeps all jobs viable. Look at raiding in classic WoW, nearly everyone is a dps warrior because it's just that much better than every other choice. That's what you get when you don't design games properly. Snowflake job design ends up hurting the game more than it ends up bringing to the table. Jobs are already extremely unique in this game, like I said before: the same timing is not the same activity. It's just good standardization. There's a big difference between the word standardization and the word homogenization. That's what this game really has going on with it too. That's why I was so confused about how people keep talking about homogenization, because there really isn't a problem with homogenization in this game. The standardization of burst windows though, yes, this is a real thing. It's why people don't care about what job you play, because every job lines up with the raid buffs and is more or less balanced. Sure there are some problems like mch that likely need buffs, but even ranged phys has utility that other jobs just don't.
Like I said though, it is good that I made this thread. I finally understand where people are coming from. You think you know what you want, but you really don't. Burst profiles being aligned is a good thing, not a bad thing.
