The idea of taxing classes because of utility skills is honestly an odd decision in the current state of FFXIV design. Every dps class has some kind of mitigation: feint, addle, phys range mit that all do the same thing but have different names. Every other utility skill is superfluous, since none of them provide a necessary benefit. The added healing from mantra, improvisation, curing waltz, and arcane crest are all honestly pretty unnoticeable in even savage content, and there are almost never things used need Warden's paean for in high end content. Same with stuns, sleeps, binds, or any other disabling ability.

At the end of the day, all that matters is bringing the bare minimum healing and mitigation required to keep people alive, something accomplished by just the healers and tanks alone practically, and everything else that matters is damage. This makes the DPS number disparity between roles, as well as classes in the same role, extremely problematic. If they are not going to design fights to require at least some utility skills, even at higher item levels, then they need to balance all classes into a similar spot DPS wise.
