I couldn't agree more about the desire for an increased Fireteam size. I (somewhat) understand the 3-player limit for Strikes but Exploring should be almost as big as you want. Why is it okay for me (and my 2 friends) to roam around Old Russia with 3 or 4 other randoms but not with a Fireteam made up of the same total amount of players (i.e. 6)? The fact that this has been a discussion before the Beta (and Alpha) was even released indicates there is much concern in the community: http://www.bungie.net/en/Forum/Post/64927990/0/0/1
