I remember running that circle quite well, I'm back to it in year 2. I made several feedback posts encouraging making planetary materials a purchased resource. They introduced marks for resources trading system. Y2 took that great idea and -blam!-ered it all the way up. Now that there marks are consolidated, purchase more items, and are less plentiful than the two mark system I am can no longer purchase planetary items because I'm using marks for everything else. Thus back to that no fun circle running. 3 of Coins does not create some magical replay value for old content. Especially when you can spend 25 coins and not see a single exotic.
