Meh.
Is not terrible, but I not sure If they match in fight dynamic.
Ok, I just looked again at their arguments again. Is not horrible I guess? I gonna try to play devil's advocate
So, they say Firefly destroying the planet was probally false, using her Character Story for the game. There, It stated she used a bomb that can destroy the entire planet to wipe out the swarm.
And the next part of her profile is meeting Kafka. Her profile don't mention the part where she destroyed the planet or crying and growing a sprout. The 'dream' part they say is only tecnically, when she entered penacomy dreamscape,
The dreamscape simulated her memories as a "dream" for her.
Not a literall one, is just the word she using to describe.
I not blaming them for reaching that conclusion, but 3.8 makes Firefly destroying the planet more legit so whatever.
