I'm bored when I heal because I need more complex DPS rotations

I think the most common reasoning of why SB was "bad" is that there was a static meta comp for the entire expansion. Although that doesn't mean that balance was bad, all jobs were able to clear content after all.

Honestly, I didn't actually see any PF lock out any jobs aside from the log run PFs who lock in DRG/NIN/BRD.

Stormblood's sins were more around the story and Zenos not being a particularly compelling villain. Content wise the expansion was fine outside of what you mentioned and possibly heaven on high being a bit of a hit or miss thing. There were more people back then who needed deep dungeons as an alternative for leveling alts.

This expansion it was the heavy push on savage and ultimate content with the new mits matters design. For people who were already doing ultimates and savage before Shadowbringers the content was probably fine, but the crowd of people that got into savage during Shadowbringers and didn't really have the time to do ultimate, and have lower coordination than the main crowd, it was pretty crushing as there really wasn't much they can do outside of it. Variant dungeons are over very fast, the new deep dungeon only works for levels 81-90 and a lot of people already had the jobs they wanted leveled, cross server travel plus mobile like gameplay of island sanctuary limited that content, so all that was left was heavy grind content like mount farming or pvp.

The relic also doesn't make use of older content to keep it fresh and is primarily using the mid tier tomestone, which outside of hunts comes mostly from the roulette. This also made upgrading crafted gear using the "rain" items cumbersome as the same resource being used for the upgraded crafting gear is getting used for the relic.
