I agree that Quartermaster should take Materials for Marks and Marks for Materials. So no matter what your "play style" is , you can afford the gear required. Even trading materials for Crucible Marks should be considered as people may like the look / perks of certain weapons and armour but dont like crucible. Same goes to players who dont like PVE but like the PVE items. Bungie - why take away something that was there from the start ?? Adding to the game makes sense , Taking things away that were there from the start is bad. Personally i liked running bounties and doing patrols while farming for materials. then being able to trade in for marks. I found i was taking just as long to do a few strikes and earn the marks, as i was to do a few patrols and trade materials in for marks. When DLC's are released , Armour and Weapons get a jazz up and you need to redo everything again and again ,so make it viable to allow different types of upgrade ways to suit each persons preferred style of game play. A FEW IDEAS . ( Introducing more ways to trade from vendor to vendor such as : Guns for Armour, - trade them ( but with a lower value) -ie. 2 guns for 1 random Armour piece of same colour etc. Engrams for reputation/marks - blues and above traded for rep / marks , or vice versa to get random engrams from makrs / rep ALSO , ORBIT VAULT ACCESS - should be added asap... swapping stuff from character to character is a nightmare ! Takes so long to get into Tower drop off gear into vault , swap characters , go back to Tower , load up gear.. etc etc.. Orbit access vault should also allow you to see what each of your characters has in their inventory and drag and drop where required. Even if its limited to show one character at a time , this is much quicker than going to tower each time . OR , just allow destiny apps / wesbite to be able to make changes to your character. !!! Easy ! :)
