Say or urging? What picks don't you think an HC has a major say in?
Man, you really are a glutton for punishment. And just so you know, I don't "bludgeon" people for links when they have opinions. Everyone is entitled to believe that Whaley is a better GM than Nix. Or vice versa. But when someone makes a strong claim, "Gailey urged Nix to take Dareus/Mario," i.e. something out of the ordinary of the normal GM/HC collaboration, I'd love to hear why they think that. Your answer, so far, has been "no u."
Some folks cite inside sources. I buy that. Some folks pull up links, that's fine too. Some folks just say "my brain thinks it!" and that's a bit harder to swallow.
