For my case, i would at least have loved for them to make role quests but with our old job quest trainers/npc
(with so much classes being made in the long run, and with their staff not growing that much, it makes sense unfortunately that they can't really make those job quests anymore, would be too much with all they have to do, well that's what comes to my mind, if you have more info feel free to corret/inform me ><)

Like having all those tank characters meet for a quest all together would have been cool i think, instead of a new character that we'll probably never see again in our entire life (doesn't stop them from introducing those with our old job trainers of course)

But as told, that doesn't resolve the biggest issue of, who trained me when it comes to this particular new spell
