My suggesting is what it always is, Go back to having jobs and roles be synergistic with one another. Go back What we had in Stormblood. It worked, fans loved it, allowed for nuance. But with this actually expand upon the roles different abilites, make CC matter, let roles have group based mitigation back, get back to when tanks and healers actually subverted the Holy Trinity of MMOs. the things that actually made XIV different from other MMOs.
