The example is only really relevant for one or two lockouts , and rarely relevant in guilds who are into semiserious mythic progression as there is usually an implied understanding of who gets loot and when . Legendaries are completely RNG . You can have two carbon copies of a character and one can end up getting 14 legendaries within a couple of weeks while it takes the second copy months to get their first with no control over which legendary he gets . <| sep |> Data is lost on video compression . The idea is you get rid of the detail that nobody will actually see to compress it . eg a JPEG image uses tricks like how our eyes can ' t really tell the difference between similar shades so the compression throws away the fact that there ' s , say , 100 really close shades of blue in the sky and says there ' s just 1 or 2 . Then you ' ve essentially got a much simpler picture and simpler , more repetitive data compresses better . But you ' ve lost the detail of the shades of blue , for ever .
