We had this topic come up when someone's vigilance was higher than cool and they thought they were being penalized for being prepared. My GM told him that, if he wanted to go in unprepared, he should holster his weapon, put away the things he took out for the fight and walk in backwards. While he might get the better roll if he wasn't, he was certainly a lot better off being prepared. I don't know if that works all the time but it seems to have put an end to that discussion.
Plus, unless you're alone, you're just rolling to create a slot in the list. The group's going to allocate which PC goes where and what each player rolled isn't important. Even if you roll high, you might go last based on what you can do vs. what's needed up front.
--emphasis mine--
Exactly! And well put. The initiative roll in EotE is not actually determining the order like most games, it is determining what might be called a potential order.
Nice post.
