I'm done with buying and crafting MSoG cards, I'm not using any real money for around 150+ pack that I get, pure buying with in-game gold.
I want listing what important card that I crafting with dust, its maybe can help other which card that worth crafting and not based from what I experiencing
Legendary / Important epic that I get from pack:
Hobert, instant dust, you don't need it for aggro warrior at all
Standard and Golden Kazakus, sadly I get both after crafting one
Knuckle, crap, instant dust
Wickerflame, meh.. but I keep it, one day Paladin may good so I can use the card.
Patches, another dupe after I craft one
so I'm not very fortunate with legendary that I get from pack.
Card that I crafting in MSoG:
Patches, absolute broken card.. its worth crafting because most deck in meta play it.
Kazakus, another absolute bananas craft worthy card and run in reno deck, this meta theme is Kazakus vs Patches afterall
Aya Blackpaw, its very clear 3rd best card of expansion.. but its only get run in Jade Decks, after next month nerf her inclusion in aggro shaman became iffy, and with that she may became exclusive to Jade Decks, so decision to craft her depend if you can see playing Jade Shaman or Jade Druid a lot.
White Eyes, I craft him because want to try Control Shaman, turned out you don't even need him in optimal list but eh I still like the card, worth crafting if you had extensive shaman card collection to play more different shaman deck than you see in meta.
Inkmaster Solia: I want to play reno mage a lot because I have most of its staple card like Antonidas, Alex and Ice Block, but the standard reno mage list really boring to play for me so that plan halted for so long, until reno mage with more burn like pyroblast discovered and I want to try it so I craft Solia, and finally reno mage click with me! I have blast with this reno mage with more burn.. so I don't regret this craft.
Some Epic:
Dragonfire Potion, I maybe craft one more too much but whatever still worth crafting if get urge/quest to play Dragon Priest
Dirty Rat, great utility card that run in most reno deck and even run in control warrior/shaman, I only craft one, really lucky to get another in pack
Rat Pack, I only get one from pack, I maybe had to craft another one because if Hunter made a comeback this card will be big part of it,
I think that conclude for card that I want to get from MSoG, its a shame I don't get Raza but I think Reno Priest not offer that much different experience so I'm not craft it.
