So, I beat the campaign, I got alot of the collectables and such, theres still some side-quests to clean up and things like that, i'm not at 100%, but I also wanna start up a new game and go through it again picking different sides in the moral choices & what not, but guess what? Continuing with Ubi's recent tradition this game does not have multiple slots for save games. Watch_Dogs didn't have them, and AC:Unity doesn't have any. What gives? FarCry 3 had 3 save slots, All the old Assassin's Creed games had them.. I don't get it, I liked having the freedom of playing these games multiple times without having to sacrifice my save files....
Is the PS4 you're on your "primary PS4"? If so, any additional account on that PS4 that has a PSN account tied to it can use PS+. In other words, you can create multiple PS+ accounts while only paying for the initial PS+ account, so long as that PS4 remains your "primary PS4".
Granted, this doesn't really help with the issue of having to log out of your primary and into the alt account, but at least you'll be able to do coop on that alt account should you desire to.
