Me and many other level 30 players don't need the marks and reputation anymore. Every week we have 200 vanguard and crucible marks but can't do anything with it except buy legendary gears and break it down for shards. We have been farming for hours and hours to get the materials but srsly, you don't wanna do it once you have reached level 30. I am glad we can use marks to buy materials from the vendors. 10 marks for 20 materials is a good price. I still enjoy doing patrols because of the public events :)
