Given MMOs are so you can play with your friends and strangers alike I feel this game does the worst job at a coop/play with friends mode ever. Not only is the MSQ a solo experience but there are even those instanced battles where you can't take anyone with you as well. Only mainstream duties are available as a cooperative experience and they only happen ever so often during hours of solo MSQ. The PVP is a solo experience too. They are scared people in VC may have an edge in PVP against others and force you to play CC alone and yet shrug it off when a ton of players cheat in PVP using mods and hacks or whatever.
This game feels like it's a solo experience for people who don't have friends but want the presence of other strangers moving around in the same game so they don't feel lonely. Even if they're not actually doing anything together.
