First of all, I'd like to say this was really well written. Nice job.
What you talked about here really touched on why the Forge feels much more frustrating than the Gorge; teamwork matters much more in the Forge than the Gorge, and it is very possible that one player can ruin the match for everyone. The Gorge was built in a way where cooperating could only improve everyone's chances, as doing it alone was possible, but difficult.
I also really agree with what's being said here, the Gorge and the Forge are definitely two extremes in the game, where the Forge demanded complete cooperation while the Gorge had massive room for error.
Hopefully, for event three, Klei finds a balance between those extremes, where the game can be fun without being overly stressful.
