Newer people either don't have SMN or Alex. WHY NOT FACTOR THAT IN?!
Because there are tons of older people around who do have it and can help, that's why. I've helped a whole bunch of people with the limit break quest. Many people needing the limit break quest aren't even newer players, they're older players who took a break. A friend of mine just did this. He'd played for years, and quit after 90 cap. He came back, and I told him "You have SMN. Just get a bunch of DDs, use inferno howl, then perfect defense, sit back and watch the fight win itself."

However, it did not guarantee a win
You really should not EVER lose with this. If you are, then you lost on purpose or played with people who don't know how to target an enemy and press the attack button (or you didn't use inferno howl).
