Isn't there a better way to distribute raid loot? If not which is most fair?

[DrKvothe]

I never understood why a straight up /random, conducted either by leadership or actual players, isn't considered fair. Show up to twice as many raids, get twice as many items. Keeps from zerg recruiting when senior members understand they'll be losing items to the new guys, but encourages participation because every raid could be the raid you get your item!

"I've spent more time at this camp so I get first dibs" has never been the way we determine 6-man loot, right?
