Though it’s possible to obtain boosters for Vanguard, Crucible and House of Judgment from Sterling Treasures in Destiny, Bungie has reduced their drop rate with a recent update. While Rise of Iron will bring Radiant Treasures that will also likely drop for free (along with being purchased from Eververse), it seems the boosters can just be purchased separately for real money.
This is somewhat pay to win in the sense that they allow for increased reputation gain which then allows for packages to drop faster and for players to obtain gear that will actually affect their Light level. Again, if Radiant Treasures are offered for free on a weekly basis, it might help concerns but only a bit.
The expansion will also bring some new emotes to Eververse including a jump shot emote, winded emote and foot tapping emote. New dances will also be included like Gangnam Style, MJ’s iconic Beat It and the Stanky Leg. So that’s a thing.
Rise of Iron will be releasing on September 20th for Xbox One and PS4.
