I like how it's a random drop actually. I haven't gotten it to drop (yet) (praises RNGzuz) and I also enjoy the anticipation. Like another fella wrote it is the excitement of not knowing when it will drop which makes for a better surprise. I liked how they integrated certain daily missions with secret areas and bosses to get exotic quests such as No Time To Explain and the Black Spindle. I hope that they bring that back with this new Iron Lord expansion.
