It does mean that a social aspect is expected and more importantly if one want to do Multiplayer content they can easily find others to do it with them though.
Sorry but I do not agree with you. Being social is only one aspect of a mmo. Teaming should always be an option, however, forced teaming has always lead to a game to fail. I remember back when I played City of. I waited 5 hours shouting out to any team. In that time I received none, no messages no invites, nothing. I wasted a night of gaming. If that is the type of mmo game you want, then I will look some where else.
When I do team, I have a blast, when I don't then I still have a blast. Like I said teaming should be optional, not mandatory. My fun and enjoyment should not be dictated by team only. I respect your opinion, even though in mine you are wrong.
That is why I like games such as TSW and Star Wars the Old Republic, these have an optional teaming, while keeping some content for that vary reasons.
