From what I gather new players to qualify for refer a friend must have owned Forsaken for less than 7 days, not the base game. [quote] New Player Requirements A new player is any player who does not own Destiny 2: Forsaken, or has owned it for less than 7 days. Once a player has owned Destiny 2: Forsaken for longer than 7 days, they are no longer eligible to be referred for the Refer-a-Friend promotion. Once referred, the quest may completed at any time.[/quote] But also Players who purchased Forsaken between October 16th-30th will qualify as a new player and be eligible for referral up to November 7, 2018. https://www.bungie.net/en/Explore/Detail/News/47367
