Duty roulette xp consumables

[Jojoya]

Like I said, I'm not entirely against the idea, but my general opinion is if you want to level another job you should be playing that job, not giving it exp items and capping it without ever playing it.

I agree with you but SE has shown they're open to players earning XP for a job by playing a different job (see PvP).

It could be they leave it as a PvP specific perk to encourage PvP participation but if tank/healer participation in roulettes ever dropped very low, they might consider adding the OP's suggestion. For now, I doubt queues are in such bad shape that they feel it's necessary.
