Long story short AIS are undertuned on NA as outlined by here. I am also a bit stupid and don't know the proper AIS rotation despite being some years JP vet so like a true grug I just got out of the robot and smashed the bug with my sharp stick. I not only ended up being twice as fast as my AIS tries, but also outdid my EP5 JP servers run with much better gear due to massive powercreep with balancing updates.

This quest is pretty fun unless you're like a Fighter I guess.
