There has been some confusion about a couple

There has been some confusion about a couple aspects of Flexible mode raiding which we’re hoping to clarify for you here:

-If all members of a Flexible mode raid have killed specific bosses within a wing, when they queue up again the next day, they will begin where they left off.
Example: All 14 players in the raid wow gold on day one have defeated Immerseus, but only 12 continued on to take down the Fallen Protectors. If that same group of 14 were to re-queue for the same wing the following day, they would begin at the Protectors with Immerseus remaining defeated. If they returned with the original 12 that downed the first two bosses, they’d carry on to Norushen.

-While Flexible mode will never scale in difficultly below 10 players, you can still queue up and begin clearing the instance with as few as 7 players in the raid.
Example: You have 9 guild members and friends who are online and ready to rock Flexible mode, but the other buy wow gold 5 members of the raid are running a bit behind. You can still form a raid group and queue for Flexible Siege of Orgrimmar, and then head inside to begin taking down trash as you wait for the others to log in
