The Exotic Weapon Bounty with crucible requirements are laughable. Not only are you forced to use one specific damage type, you are also forced to go massively positive every game with those weapons in order to get any progress in them. The death removing progress on the bounty encourages people to quit instead of continuing to play losing games, reducing the enjoyment of everyone else in the game. These steps are absurd when you can easily get an exotic just playing the crucible without the restrictions and doing poorly.
EDIT: Apparently you even lose progress if you die while the game is over and the score screen is being shown. That's absolutely retarded.

Well, exotics are the rarest and most powerful weapons in the game so far, so naturally they should only be earned by someone who is extremely interested in and devoted to working for them through challenging requirements. Nobody is forcing you to do this bounty, and if you don't want to do the work to get it than you don't deserve to have an exotic weapon, that's the point if the bounty/difficulty in getting all powerful items.
