Nothing is wrong with them the issues that had been in the game regarding exotics were fixed last week exotics do not need a drop rate buff they're meant to be rare and now it shouldn't be an issue getting new ones (short personal story) took me 330 days to get my first gally grinding since beta on 3 characters everyday dropped it from VOG chest a week/half before xur sold it a second time that is around 330 days since destiny 1's launch
