Turn 5 Downed by JP Group? Exploits or Legit?

Why is it so far fetched that no team has figured it out yet? BG thinks its fine. So all of a sudden, unbeaten = broken? Lol

From what I recall (I may be wrong), they're only notable for FFXI, which is extremely low on the skill requirement scale.
I wouldn't take them as an authority on anything outside of theorycrafting, unless I'm wrong and they have do notable achievements in other MMOs with higher skill requirements.

Aside from that, they tend to over-praise SE.

Turn 2's boss is extraordinarily well-tuned and requires the utmost execution from every single person in the party. The fights are well beyond our expectations. Thank you, Yoshida and the battle team.
