All guilds die eventually. No guild is indestructible. That why when I see these guilds with huge egos die out after a few months I laugh my ass off. My old guild that booted me before Wod for missing a measly 2 out of 30 raid days thought they were invincible and disbanded a few months later which also made me laugh my ass off.
That said, I hope the players that are left land on their feet elsewhere. I'm willing to bet some of them end up back in Method.
