How about not ever earning an exotic from a drop, chest, or raid? I've had to buy all mine or do exotic bounties to get them. And I've had the game with three separate characters since it came out. All those Nightfall Strikes and Engrams and Raids...and nothing. And the thing that pisses me off the most is the fact that I've beaten the VoG on hard 19 times and I haven't got the Vex Mythoclast. 19. Freakin. Times. Makes me wanna quit this game.
