I dont see how any of this is a problem - this isnt an MMO and to be honest this game isnt fun with random people anyways (and not made for that aswell) since most progression etc. is bound to the server. So either play the game alone - no problems - or with a group of people you know (or look for a group) - no problem aswell ...

If you are looking for some sort of competitive MMORPG etc. this game probably is the wrong choice.
