I think pairing is most important for me? Followed by warning but only if it's someone who has a habit of writing het. It doesn't have to be a pairing like X+Y-with-a-little-bit-of-Z kind of descriptive pairing, just X+Y will do. I really like any pairing as long as it's hawt, but if it happens to be X+A Where X is male and A is female, then I may think twice about reading it.

Not that I can't handle het... I don't mind het if it's cute and fluffy. I just am not too big on het pr0nz.
