Let me start by saying I am aware of the distinct possibility that I am in the minority here and that many may disagree with me.
I do not like the Role Quest system, specifically I do not like the fact there is lore and story locked behind them that is irrelevant to your role/class.
In the past when we had Job quests, the stories were usually about that job, the culture surrounding it and other characters who were that job. They were very hit and miss, some were great, others were garbage (Paladin). But to my knowledge they never strayed too far from the lore of the job and how it functions, so of course it made sense that you needed to be that job to do those quests.
Now we have Role Quests, which are much broader and have a wider reach in terms of plot and characters involved, the lore in these quests generally don't pertain strictly to that role for the most part (there are some exceptions).
As somebody who has no interest in playing all role types and does not wish to level other role types, but cares about lore and story, I find this to be a bit of a headache.
Why should I have to level a healer to see the continuation Unukalhai's story and their attempts to investigate the void which is arguably MSQ relevant. Why should players be blocked from this extra content because of of their choice in class, the content it's self has literally nothing to do with roles or classes, it's ridiculous.
Would it kill Square Enix to make it so Role Quests were instead just quests that you could do as any combat role. If you need a contrivance to hand out AF gear then you could still have it so certain ones allowed you to get certain AF sets, that part is fine.
It feels as though you are punishing players who just want to enjoy lore and character development that is complimentary to the MSQ, due to their class preference, Job Quests did not have this effect.
All this isn't to say I miss Job Quests, I don't. I just feel that Role Quests should either be changed to be "normal" quests that happen to unlock AF Gear but don't need specific roles, or the content behind them should only require any one of the role quests to be done. (I'm aware the latter causes narrative issues)
Please Square Enix, let me rescue Unukalhai from the Rising Stones without being forced to play classes I don't wish to play.
