I find some of the responses a bit baffling: [b]1. They had to remove it because if you can get mats for marks, and then marks for mats ... you would exploit the currency[/b] I'm sorry what? You got 5 marks for 50 materials. Now you get 20 materials for 10 marks. So I farm 100 materials. I get 10 marks. I trade that. I get 20 materials. I now have 0 marks and 20 materials. I just lost 80 materials. Clearly I am a criminal mastermind who must be stopped. [b]Crucible marks are for Crucible weapons[/b] I keep reading this in the forums over and over and over again. There are three main problems with it: 1) The only "crucible" weapons in the game are the ones exclusive to crucible drops or the crucible vendors. Just like a Dead Orbit weapon is only available from Dead Orbit. They're just another manufacturer. By this logic, you should only earn Dead Orbit marks for Dead Orbit weapons. 2) Yes, some weapons are better in PvP than PvE. Guess what - some of them are made by the Vanguard. So, there goes that theory. 3) If anything, the various factions should take Vanguard marks since they are the ones responsible for patrol missions (not Crucible matches). Personally, I never sold my mats for marks because I found it faster to just do a strike or public event. But if people really enjoyed farming patrols - I don't see any valid reason not to reward them for it. Bungie themselves say they want to "expand your play". It would be nice to see them actually do that.
