There's only two vendors for Vanguards. There's 5 for Crucible. If they allowed using Vanguard Marks for the Factions, that would alleviate some of my issue, even though two of the weapons I want are only available from that vendor. The other problem is that I now have no use for my excess farming materials beyond discarding them, which sucks. I can see giving people more options, but don't take others away. There's now no incentive to farm. Remove the need, not the incentive.
