For each expansion, I've always assumed that they'll add at least one job for each roll.
This got me thinking though...what FF jobs could be added as new healers past Stormblood?
Generally, XIV seems to try and stick the traditional role/weapon/abilities for each job (though this isn't applied to Dark Knight or Bard), so I think we can figure out which jobs fit into the 'healer' role by looking at how they are in previous FF's.
In previous FF's there are a many jobs that can dedicate themselves to healing/support. White Mage and Scholar are currently in-game, and Astrologian is a mix of FF Tactics and concepts unique to XIV.
So, this means out of the jobs that could fit into an MMO 'healer' role we could have Red Mage, Chemist, Dancer, Sage. Chemist and Dancer are both support oriented jobs in most FF's, but I think they'd fit in as healers better than they would as support dps. Bard in the form it takes in previous FF's would be another good candidate for a healer, but it's unfortunately already in use. Jobs that are considered 'upgrades' of healer jobs (e.g Devout in FFIII) could also be included, though they'd have to deviate pretty heavily from the traditional image to give it a concrete identity.
I'd love to hear what other jobs people could see being added as a 'healer' job.
Personally I really hope they do end up adding Dancer as a healer in Stormblood, but for all we know it could be something completely new and unexpected!
