158 packs, 9 Legendaries, including the ones from the mega bundle and the free one. That gives an average of 1 every 21 packages. The good part is that they Gave me Golden Dr. Boom so I saved 3200 dust right there. Also got Unstable Element which I really wanted but haven't got the chance to make it work just yet. Also got 33 epics (2 golden) and Whizbang :) and Harbinger Celestia :(
I didn't get to take any sc's but this is what i got:
The free class legendary- Zerek, Master Cloner- Pretty cool
Two golden legendaries- Whizbang the Wonderful- YOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO Myra Rotspring- eh i dont play deathrattle rogue
Packed Legends from the 133 packs- Floop's Glorious Gloop- Would be good if i got Floop himself Zilliax- YOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO (he's in my mech paladin deck) The Boomship- I got this early on so i had hope i would've got Dr. Boom but i didn't so i had a poker face. The Soularium - I heard its pretty good warlock so i was pretty happy. Zerek's Cloning Gallery- Felt eh cause it has potential i havent tried working with it yet tho. Boommaster Flark- Pretty cool Flark's Boom-Zooka- I dont like this card
I had 7235 dust so i crafted Kangor's Endless Army (Which has been doing really good)
I can't really say I want any other cards, maybe subject 9 if secret mech hunter becomes a thing, other than that i pretty much got everything I wanted so yay me.
Third expansion in a row I got none of the legendaries I wanted, and well under the average for legendaries and epics. My alt account got 2 legendaries in the first 20 packs, not counting the "free" one. I was F2P up until last expansion, might go back to it.
Opened 20 packs and got two legendaries which was pretty decent. Went to work and came back and did a daily to open one more pack and got two legendaries. So 21 packs 4 legendaries + my free one for 5 total. I didn't want any of them but I still have enough dust to craft two anyway.
What really killed me is I got 5 epics and 4 of them were loose specimen. I mean I guess 200 dust is okay but dang I could have used almost any other epic cards
