I really, REALLY don't understand this mindset where people believe no job should even be nerfed :/

No, okay, I lied.
I kind of get it.
People with a certain main that is currently in the spotlight for that certain role don't want to see their job changed, they want it to be relevent and good and AWESOME. I don't blame you for it, really, although I don't main any of the three tanks I do main a job that saw some serious nerfing in SB and as it had been amazing in HW, obviously I was not overly happy.

Please undertand though, that simply buffing and keep on buffing all jobs until they're equal could just create more problems than it's worth.

A tank with awesome survivability AND topdps at the same time like WAR was back in HW? I mean, okay, it was a thing to behold, but you can't simply buff up other tanks to its level. It would mess up not only the TANK balance but it would also drag in other roles: DPS crying about tanks having too much utility and them being redundant. tanks being shunned for not stance dancing because they're supposed to DPS because they're able to pull amazing numbers and so THEY HAVE to stance dance, etc.

A healer with too potent heals? Let's just amp up all other healer classes to HW level where they could just DPS all the damn time. Dude, as much as I like to help out and DPS, it gets boring.

A DPS with too high numbers? Well, let's increase potencies and reduce skill costs for all other DPS jobs so stuff can be burnt down so quick you won't have time to sneeze midfight anymore or risk it being over

The above examples are obvious exaggerations, but I hope I was able to make a point somewhat?
Buffing all jobs in certain role won't mess ONLY with the dynamics of that role - it will mess with other roles as well, and will implicate that BESIDES the role changes all other content would have to be revised so teams won't be too OP to clear stuff with literally no challange.

... and let's be honest, that's such a minor change I wouldn't even consider it a nerf...

tl;dr: can't just keep on buffing up classes, my dude, there'd cease to be an actual point in like, running content lmao
