Oh, and also, I would advise revising that "two major characters" rule. Only because, say, does that really make Harry/Remus or Remus/Draco, etc. a non-rarepair? Cause I'd say they are. Or Draco/Snape (def. NOT a common pairing). It might be best to keep it to defined rarepairs, and just make an exact list of what isn't rare, to avoid confusion.
