I accidentally traded all of my vanguard marks for spirit bloom because I thought I was trading in what I had collected. The patch notes were vague and I clicked too fast to realize my Vanguard marks were going down and not up. I just figured they changed the trade-in rate to 20 instead of 50. Now, I have 200 spirit bloom which I have never seen any item need for upgrades and 8 Vanguard marks when I was saving them to buy some armor. Bungie should have communicated this better and/or changed "Materials Exchange" to "Purchase Materials". Also, if they want people to play the Crucible more, maybe they should add more/better maps. BTW, I played crucible and it was ok, but I found myself simply doing PVE stuff more often so kind of settled into that groove.
