Dragoon has its uses in some of the current "end-game" effects for the game, namely Voidwatch and Legion.
Voidwatch they're useful partially because the stagger system for Voidwatch can encompass the specific abilities of any job in the game, so it's common for a Dragoon to be brought in to cover those abilities. Not to mention they have access to all the Polearm weaponskills (which are also potential staggers) and can hold their own as far as DDing is concerned.
In Legion, it's common to have at least a party of strong DDs and a good Dragoon (as in Relic/Mythic Dragoon) is able to also hold their own in there. Angon, especially when fully merited, offers a decently long and potent Defense Down effect, so having that at their disposal to tag mobs with is always great.
I would assume that in Neo-Limbus and Neo-Einherjar they could have their uses, but a lot of those use a more old-school method of fighting those mobs as opposed to just TP burning mobs nowadays.
