You must have skipped past the part where I mentioned that they could have just removed the reputation/glimmer and kept the mark exchange. And before you go into exchanging 1 Mark for the other, consider the following: 10:1 materials for marks + 1:2 marks for materials = 5:1 Mark for Mark Since each mark you gain adds to your 100 weekly cap, yet the ones you spend do not subtract from it, you would have to max 1 type of mark for just 20 of the other, which would leave you unable to gain anymore of that 1st type for the week. Thats a pretty steep cost.
