For instance, in the new campaign we have quite a ways to go ahead of us. Its easier to keep one character around in the core from beginning to end, but I can imagine I will want 2 sets of characters leveling throughout a campaign. It makes it especially safer for when you lose a pair and there are not infinite upgrades anyways so you might as well have two parties kicking around.
So, is it supposed to be in a way that you can read the intro and try to understand whether your investigative pair should have been assigned to this adventure or your monster hunting team(just an example) and then decide who is participating? I understand the openness here on coop play but was wondering if this was spelled out somewhere?
