Makes shifting Weapon Parts and Materials so much easier. Now they just need to do the following: -Remove the stack limit on Materials. 200 is ridculous, should be like the Armour and Weapon materials, be able to have stacks into the 1000s to save space. - Re-introduce trading Materials for Marks, Vanguard or Crucible - Trade Commendations for Marks, because I'm sitting on a stack of 20 Crucible commendations that are useless because I don't do PVP. They should probably just turn Xur into the Black Market trader, where you can go to him every week and change your Marks/Commendations from VG into CB and vice versa; and give the Quatermasters the ability to take materials in exchange for Marks again, if they're not going to give Vendors the option to take both currencies. Maybe with the new Reef Social Space thats been touted by rumours we'll get currency exchange, Destiny really needs it to give you more depth and range of choice no matter what you play, PvE or PvP.
