I'm not getting rid of my library sets because I want the CC's they give since crafting something all the time is important to me. I also use the smaller buildings to supplement my mana and seeds. With the new Residue badge in the FA, I ran very low on CC's and time boosters. The Spire is a source for both of those, but mainly the time boosters. CC's are less prevalent in my direct Spire rewards. Obviously, looking at my inventory, I'm not flooding the market with the excess scrolls, either. I figure they're not hurting anything just sitting there growing larger... For my neighborhood, scrolls were already the most offered item in regular goods trading even before the Spire came out; it's just amplified to me when compared to my inventory.
