thats only the groups that KILLED Oryx not how many have tryed and failed there are tons of people grinding light and trying to get on raid teams but honestly its a little to much for some players then you got all the casual players that cant spend that 2+ hours to get your team right to clear the raid (i say 2+ since thats how long it took us to clear it when i ran it with a group of 5 friends who never made it pass the 2nd boss and we got all chest to) there is a lot of comunication needed to beat this and also you need to be able to deal enough damage on some points and i still think not many understand how to do this clearly at this time that number will go up shortly i know many that have cleared it with teams of players that have never and they are in turn helping others so soon more and more teams will be clearing it. also bungie has to be happy they made this one a challenge and 12K fire teams is all that managed to beat it so far but the true question is 12K fireteams = ????? many players since some of them would of cleared it with multiple fire teams
