Turn 5 Downed by JP Group? Exploits or Legit?

[Sephirah]

While I totally agree that the fight isn't a big gear check, you can clearly see he's wearing a Hoplite Tabard from AK in the screenshot.

The AK Hoplite Tabard is irrelevant. For a PLD to have 5.8k without a food buff, all their other equipment is some combination of DL/AF2/Allagan gear. With food I'm at 5.8k and I'm in full dl, minus still having the AK necklace, and all but 4 of my bonus points in vit (which I plan on fixing soon).

(Edit: that being said, this was still not a legit kill, and the FC that did it is not trying to claim it was)
