I think not exaggerate anything else, as well as a taste for couples and attack the same, because both are going to extremes, I'm a fan of NaLu but rarely mention the act, being that I like the couple for years and am confident that the author give aunqeu is the end, but if not given and prefer the open end like not bother me, because I know it could be for a reason.
I do not think either that it can blame Aya Hirano and Voiced Silver, if you're going to blame someone blame the person who climbed an incomplete interview and incomplete context, both Aya and the other Voiced spoke of something definitive for series itself, they spoke the arc de Tatars, and that if there were scenes more "Romance" between pairs of Gajeel and Levy and Gray and Juvia, and the reason he gave the author that in this arc not there would be something between Natsu and Lucy because I did not want to mix so many things at once.
So I say, do not blame, it would be the person who climbed incomplete information, to cause something he knew could come crashing if not gave everything correctly. You might even be that it was a malicious way miss.
Now, although we though there are people who buisca siemrpe create conflict and discredit the work, characters and fans, we really can not avoid unfortunately, all the popular series have them, the joke is not to be manipulated by them, but overcome to be able to avoid fall into their tricks
