Not really - I was saving them to sell, mostly. Glowing Contagion is north of 150,000 treasure on the AH, while A Little Universe is the much more reasonable 75,000 treasure. I'd happily accept 75,000 and 35,000 for them, or an Underbelly scroll (marketplace price 150,000 treasure) for both; the only thing on my wishlist that's cheaper than Underbelly is a Black Aviator Scarf (gem marketplace item, 125 gems, which at 1:725 is 90,625 treasure).
