No more blue coin challenges???

Has anyone noticed in the last month or so that we haven't been getting any more blue coin challenges? I remember around launch getting at least 200 a day from challenges, and now I don't see anymore. I've talked to some friends and heard the same from them. This is a pretty scummy practice seeing as how that was one of their marketing points, good monetization. I don't like being forced to pay for skins that aren't legendary rarity, especially when promised they would be grindable. Feels pretty backhanded being silently patched out of grindable content, after being promised it. So I ask you, when is the last time you got challenges that reward you blue currency?
