That depends IMO.
If you were dead set on playing a particular job and said job was a dumpster fire then that's a fair view to hold.
If you were flexible on what you played then IMO it actually wasn't a bad thing at all. I did Gordias as SCH then WHM, Midas as both WHM and AST, then Creator on AST. The shifting meta and balance gave me a firm push into mixing up what I played, that alone does wonders for preventing things getting too stale and I'd credit that as a healthy portion of why I have some 80 or so A12S clears logged alone, at least half of which were PF.
Meanwhile with the current status of balance above all, I generally just sit on WHM and leave it at that as there's little to nothing to be gained from playing a different healer. Thus things got stale fast I guess.
Sometimes you've got to save the playerbase from themselves, having jobs/classes that are inherently somewhat unbalanced but with a meta that is always evolving over time helps do just that whilst FFXIV's job system means that the 'penalty' for switching to a more flavour of the month job is relatively minuscule compared to what you used to see in WoW.
