LAST EDITED ON 04-22-12 AT 09:39 PM (EST)I think there are multiple F4 established and I think all the combinations they represent are still possible. A smart player doesn't let anyone hanging.
It's not only this cast and it's not because they are feeble-minded; it's every single player that ever got blindsided. Take Palau: Gregg thought he was solid with Tom until F5. Tom got him out at F6. Tom himself thought he was good with Ian until F3. He found out he wasn't only because he won immunity at F4.
As for not knowing exactly where one stands, that is the beauty of this game. I played 6 times on-line and I never knew exactly where I stood. Twice, I got blindsided by someone I thought was my closest ally. The two games I made it to the end were the ones where I struck first against my closest ally.
(That is a reminder that I have a game starting soon if you want to join, Tuesday is the deadline)
