It always struck me as strange that they tie specific crucible modes to specific factions, but without any real explanation, benefit or unique reward. It's not like you get crucible rep AND faction rep for being good in that particular mode. Really, overall there are just way too many currencies in the game. Marks, Motes, Coins, Glimmer, Engrams, etc.... and there is not enough of an economy to justify them all. I mean seriously... If there are going to be so many currencies, they need to be more substantial. Example: -Marks universal to all Factions (including the 3 vanguard factions: Hunter, Warlock and Titan) -Glimmer universal to all Vendors -Motes Of Light no longer a currency, but an actual Upgrade Item (rather than tying Light to specific pieces of Armor which limits Customization and Uniqueness) -Strange Coins for all intergalactic commerce (which means there should be more than just Xur, put Agents of the Nine on random planets with totally unique inventory at various times of the month, and at a Higher Price. Include The Speaker in this category, as he sells Blessed Items of Galactic Origins)
