Let's not pretend for one second that everyone popping a buff button every 2m was unity. It was a rigid forceful way of making players and rotations run.
The 2m meta was the source of a large amount of the hemoginisation of classes in the game, as I pointed out before with the examples of Drk and Asto.
They used to not actually have that many OGCD buffs in the game, in fact most classes had these buffs as part of their moveset, it was only as the 2m meta started to be leaned into and more and more classes had mechanics that lined up with it that it started to really impact the game. There were many classes that were more enjoyable at heavensward before the 2m meta became such a rigid sticking point. From the Stormblood combat rework all class design was done around the 2m meta.
None of the combat mechanics in the current state of the game are complex, with the exception of ninja. I would argue about 20-30% of the classes buttons are just buffs that should be baked into weaponskills and abilities instead of press button to do x more damage for 10s or x amount more mitigation. Nothing they have talked about really feels like an actual reduction in class mechancs in fact I would argue that the dragoon evolved combat is significantly more complex than the current dragoon state. They said the bards going to focus more on procing their music instead of posions which I would argue is significantly more thematic for the class, but again none of these changes have been shown in full yet.
