I said this almost a year ago in one of my earliest topics. Its more true now than ever. Designated loot drops should be guaranteed 100%, and the only thing you should be farming is the perfect variant/anointment. Anointment and element give more than enough in terms of variation to justify this and we arent even considering weapon parts yet.
Please use one of existing topics Bonus Boss Loot is great, can we keep it this way?
