Lacking Incentive. The only time I have played in the Crucible is for exotic weapon bounties. I believe they're changing it soon. But 3 marks for a win and two for a loss? That's a glacial pace to accrue enough for a gun. What would I get from ten hours raiding and nightfall instead? Much more than one crucible or faction weapon. As for faction weapons, it makes more sense to level up the factions and see what drops on the post master. I have 7 FWC weapons, 5 dead orbit, and 3 New monarchy. If I bought them with marks, it would have taken at least 150 hours. (3 marks for a win, 5 rounds per hour = 15 marks per hour, 150 for a gun, makes ten hours play, per gun, if you never lose a round)
