Not exactly related to your topic, but I had a very interesting keg opening session earlier today: in 30 NR kegs I got 7 epics and 4 legendaries, although the third was just for scraps as sadly I had all three already. But I did get both Dandelion and Priscilla, lovely couple. And Carlo Varese.
Back on topic, Carlo was a premium as well as two rares. Very lucky today (yet sometimes I get zilch).
