"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

Well, I don't feel like replaying the campaign right now, but when I do, I'll definitely do it with a hero.
I agree about Kujin; the losses there were only due to two things: my strategic mistakes and the Temptresses who controlled the Daughters of the Earth.
Regarding the battle with Biara, yes, you're right about the blinding; I forgot about that, which is why I had problems.
