Questions you don't think SE team will answer.

the people who play tanks and healers don't like new things too so why do we have to get left out?

Someone was always going to get the short end of the stick, and if tanks and healers get a new job every expansion then two of the three types of dps would have to wait. Casters will have waited 4 years at this point for a new dps...and without a second both melee and ranged would also be waiting 4 years till the next one. If they kept that pattern up and gave melee the job for the next expansion then ranged would end up going 6 years since the last of their type was added...

While Tanks and Healers got a new one every two years.

Does that sound particularly fair to you?

They just got two new additions with Heavensward :/

Granted, not magical, but the cast bars are there.

To be fair, MCH and BRD are both caster ranged dps with the former coming out with HW (as much as they are unhappy about it) they are just physical caster dps rather than magic caster dps. A melee DPS was NIN released in patch 2.4 coinciding with the PvP update. So I will agree that it was indeed time for a melee DPS as that of all the play styles has been the longest to see a new release. It does bare concern though, and really I understand SE pretty much is going to hear complaints regardless of what they release, but saying that releasing a new healer or tank isnt going to affect the morale and wont result in the abandonment of the role for some of those 2 due to stagnation is kind of foolish. I guess they may release another mid expansion job at some point like they did with NIN but as they didnt with heavensward I am leery to place any hope on that. So as it stands healers and tanks will already be waiting 4 years for their next job and honestly for some that may be too late for maintaining their interest in the role.

Caster tanks have been waiting much longer.
Melee Healers have also been waiting much loner.

SE view them as Ranged and melee only. Not by the mechanics in which their role plays.
If we went by mechanics, or even by aesthetics, we are missing Mudra healers, mudra tanks, and or dual wield tanks and dual wield healers.
And even then, most content can be completed with full melee, or full ranged. (The only time Ive seen it difficult with either full, is in savage content where you need the LB3s, either for single target DPS checks, or AoE DPS checks. And originally Content wasnt designed with the use of the LB until more recently, due to people being picky on which jobs they bring for the LB3)
So you're argument should be "They introduced a ranged DPS, and Healer, then a melee DPS, then a ranged DPS again." not "Its been forever since we got a caster" (If you count a job based on its mechanics, then you got AST as well as MCH)
