Yeah, I have no interest in that kind of fanfic either.

The author of that post makes another interesting point - about characters whose biggest flaw is that they are "too nice and always put others ahead of themselves", and how to actually write that in an interesting way, e.g. someone who would never abandon a person in need, even when doing so is necessary to save both their lives, the team, the whole world, and all the cute fluffy bunnies. Sailor Moon at the end of S season came to my mind with that one!
