Your point about the editor wanting less than 6 enemies is especially important, as I see it, the amount of characters was the main source of downfall... cough* Naruto/ Bleach ._. So... yeah, the messy arc that we got happened, along with a lot of forgotten characters. When Mashima does remember them, I bet he's like: "Oh shit... they existed... *frantically inserts them some where to keep them relevant".
