Ingame demons and their purpose

@Lore regarding warlock pets

What exactly is the benefit of having an incubus over a Succubus? Lorewise I am aware that Incubus do exist but they were not spoken about, but why would a warlock use an Incubus anyways?

The Incubus is the shapechanged form of a Succubus. However traditionally while the Succubus symbolises seduciton, the Incubus tends to be themed more on molestation.
