There are always going to be things that don't strike me as 'perfect' in all fic, but the very last place I'd say anything about that would be in the comments section of anonymous gift fic, especially if it's about things that the anonymous author would have included at the recipient's request.

I mean, you might as well be posting a comment that says "God, your recipient was a freaking moron, asking for these elements!"

People. Feh!
