Is Severus/Lucius really a rarepair? I suppose in terms of fics written it is, though it plays a backing role in a lot of fics. I thought a lot of people shipped it, and therefore with the tiny amount of fics you'd think it'd get tonnes of feedback. But alas, no.

Technically, no. I was just making an example out of a less popular pairing that doesn't get the feedback that a more popular pairing would, regardless of artistic and intellectual content.
