If I remember correctly, FFXIV went through the usual design progression:

1. Dev decides DPS with utlility should have lower dps.
2. Progression raiders declare utility DPS garbage. Utility DPS player complains.
3. Devs try to make utility DPS useful to progression, hence utility becomes raid damage buffs.

And to ensure #3, devs have also designed all content to never require any utility. Which means there's no point designing utility skills and abilities.

This is an old debate, and FFXIV clearly chooses to do away with utility to streamline content design and simplify job balance (not in terms of dps potential but in terms of the desirability of each job).
