The situations is the following. Rigg got like 7 years of Marine experience, if you fuck up when you are down in the middle east, you are a gonner. You can not afford to do something wrong during those circumstances. Now, those 7 years of experience is still in his mind, so he is using the same attitude and discipline in the raids he is leading.
Fuck up irl and youre dead, fuck up ingame and you loose World First. Do any player in Blood legion play for world second or world third? No they don't they play for World First, as such Rigg as the raid leader can not allow any player to fuck up during his raids. Old habits die hard as they say.
