Well, the majority of gamers are 99,9% of the time online while playing pvp, coop or single player (even when internet connectivity is not required). We have mobile devices and tablets with 4G connections, our laptops/desktops are always online but when it comes to gaming people tend to react with the "always online" requirement.
This reminds me of the X1 always online requirement back in 2013 which condemned the X1 launch even when ms changed that requirement.
It is not a big deal being always online especially when it comes to features and gaming innovation
