Dramatics is a general skill that boosts influencing and ego based abilities. It's also used for debates. Everyone can use it, and make good use of it, not just Bards.
Bards happen to be the class that primarily uses ego based abilities as their combat concept/idea, so dramatics has a lot of stuff that complements their kit. It can be argued that the benefits it gives are more useful to a bard than any other archetype. However, it is not essential to a Bard. It's just really nice to have.
Dramaturgy, on the other hand, is a tertiary archetype skillset available only to bards. It is one of the three cornerstone skillsets a bard can use as part of their kit. Tertiary skillsets are, by their nature, not always essential to combat either (the primary skillset, in this case Music+Spec, is usually the only one "essential" to combat) but they instead have abilities that sort of define the "style" of the Bard's combat. Dramaturgy, specifically, is combat orientated (ie. not a utility skillset), though it has a couple of nifty RP-bard style abilities in it.
