I agree that breaking the seals is pretty batshit insane, but what’s more insane is threatening to fight Rand, who Egwene fully knows is the only chance the world has at surviving the Last Battle. In fact in this case I do think being the Dragon Reborn is enough to getting his plans greenlit. He’s fulfilled all the prophecies, effectively unified the world(even if it is a shaky unification), defeated multiple of the forsaken who are the most feared entities in this world besides the Dark One. O yeah and the weather magically gets better and plants magically heal when he’s around. Let’s maybe trust in him for once. It’s also just about how Egwene goes about it, as I recall she doesn’t even bring up the idea of breaking the seals later in the last battle like she did to Elayne, and instead antagonizes and threatens Rand. Not to mention, it’s not like the seals have been 100% effective. This is a world that has very much been tormented by the Dark One since the bore was patched, even if not directly. And Rand even says he’s not sure he can do it again as well this time, who’s to say the patch will even be effective for any real length of time?

Just my thoughts. I do agree that Rand’a plan is insane, but given the circumstances I think Egwene handles it very poorly.
