but following your logic you still gain less than you would from saving the lizardtribe even when considering the nameless. you still can choose to serve him either route, so whats the point of choosing by doing it that when you could easily just choose him anyway? plus he gets what he's after no matter what, so again if you WANT to serve him either route does perfectly fine but saving the tribe gives you more.
(btw this is me the guy above you and I'm on this because it's saying I can't reply to you and it's not telling me why so because I didn't want to ignore you I made a temporary alt.)
