What determines where a flex group will start upon porting in? For example, if I have only defeated Shaman in flex 2, if I enter my own flex, I will start at the beginning of flex 2, so Galakras, right? Is there any way to do only Nazgrim, without having to defeat Galakras and Juggernaut (without joining someone else's group)
And if I have defeated all bosses of flex 2 except Juggernaut, is that where I will start when I make my own flex?
