I'm starting to think that the more packs you get, the less your chances of obtaining legendaries. In the Witchwood and Boomsday expansions, I made do with less than 70 packs and had an average of 7 legendaries, albeit a few epics. I'll keep this in mind next time.
Ouch. Sorry to see that someone did worse than me. I managed 3 from 67. Hey, you could be on par with me if you open 2 more boosters!
Got another in my 6 free + 4 from gold. Then, really wanting more cards, I bought 40 more packs. Got one more. 15 packs. Got another. Not sure if I'll buy any more, this set just isn't giving me value! With my dust I crafted the hunter Loa. Yet to play it, but fits nicely in Quest, I think!
