Playing with friends is not necessarily a problem, in my book it's fun. Especially if you win.

Just today I asked another friend to join, as she enjoys the beard game too.
In one game I played with a friend and an unknown person, the friend asked why didn't I already attack him with major force. Well, it was just a matter of different playing style, I was biding my time to have the borders secured. He also kept agitating the third player to attack me.

Also, team games work best with friends... And another good side, at least I can phone them and nag a bit if they don't play their turn.
I also made an account for my son, but no way I'll play with him yet. He's just learning the game, so I advice him a bit, not that he always follows the advice.
