Fenrir has been around awhile. You know who almost never had a true back story? Shiva, yet people "over exaggerate" wanting her.
Garuda? Ha, yeah her too.
Ramuh? Him too. FFIX and IV After Years are the only FF games with an actual "story" tied to him that had true plot relevance - He's "just a summon" and most FF games.
By your logic a lot of these summons shouldn't be in the game except for Bahamut since Bahamut is generally the only being with a true story anchor. So no one is 'over exaggerating", FFXI just happens to be a FF game that gave story and backstories to summons that usually never had them.
