At some point, yes, I completely agree with this. But I think adding a few more classes at least is what we need to help see the current job classes eventually leading up to that.
Like, with Sage added to the trio of healers as the fourth and with the introduction of pure and shield Healer concept to seperate the Healer role into two distinct groups. If Endwalker is successful with this concept, then I think we need more of that with the job classes we already have, plus adding a few more in order to fill certain roles our current roster of classes can't at the moment. For example, with the loss of Summoner's DoT spells, this would give FFXIV team the prime opportunity to introduce a spell caster class that focuses primarily on DoT skills and status ailments.
I think after all of that, then the devs should focus on customization options, skilltrees and alt playstyles for the classes to give some variety to what we already got.
