Turn 5 Downed by JP Group? Exploits or Legit?

[Alkimi]

Many people I know flat out have no motivation to run coil past turn 4, which is probably the opposite effect SE intended

I think you can count most groups who have cleared 1-4 into that category. If even one group had beaten it legitimately then there would be a lot more motivation for others to try, but if the best players in the world are still wiping after 800 attempts then what's the point?

My group only plays around 3 hours a night, 4 days a week so the chances of us beating it are virtually nil.
