Improvisation

[LynxDubh]

MCH and BRD got extra support because DNC was just too bonker to hope competing with.
We have around one time where Warden's Pean is use per expansion, let's not count this as utility.

DNC has Samba, Curing Watlz and Improvisation. It doesn't needs any other buff that would give it another edge in the ranged role when it's been the best ranged since its introduction.

You have it backwards, MCH got extra support because DNC and BRD both were more popular than it. Now that MCH got the wrench (what I most wanted for it to get back from its HW kit) it is equally valued if not more in circles for its superior dps compared to BRD and DNC.

Warden's problem revolves around encounter design and is actually rather functional, while Improvisation suffers from both encounter design not catering to it and not functioning well for a support ability. And you know what, I want Warden's to be used more, it's also fun. Let BRDs have more usage of their interesting buttons too.

No, DNC was dominating too much the ranged role and will keep dominating the ranged role until they remove the single party utility.
Dance Partner is simply too good and now has a new potential partner, the Viper.

The problem is that you compare DNC, BRD and MCH together but you need to compare them when they're in a full team.
DNC is a job that perfectly fits in the 120s meta AND repetitive downtime design of many encounters.
DNC also works incredibly well in early savage thanks to gear funneling.

Improvisation is a 5% shield at minimum, Dismantle is 10% mitigation. Shield is often stronger than mitigation, as the more mitigation you stack the weaker it becomes, a 10% mitigation can become a 5%.
On top of that, DNC has Cure Waltz, which is the equivalent of a Medica III.

DNC has not dominated the role in its entirety as you claimed. It was a top choice for prog environments due to its support, and when BRD got the Nature's Minne buff in 6.3 it became its equal in prog. But once MCH got its buffs to damage and wrench back it shot up to the top of farm and clear content due to its reliable and superior damage profile paired with its potent mit. And let's not forget the start of EW where BRD was top dog due to the aiming gear's stats catering to its strengths and pushing it above the other two ranged. DNC is not the monolith of superiority that you're claiming it to be.

And Cure Waltz is good, but it is not equivalent to a Cure III (I'm assuming you mixed them up as Medica III in DT is a whopping 1125 potency with the regen) Not only is Cure III not a 30s cooldown, it also can be cast on a select target, has triple the radius, and its full potency is not beholden to a fidgety dps partner when the EW boss hiboxes allow them to melee out in Narnia.
