I have some spare money that I want to spend in Hearthstone. I'm a Wild player and I can't decide which option is more valuable:

- I've bought the first wing of Blackrock long ago, now I'm considering to buy the other four. It looks pretty weak compared to the other adventures, the only good legendaries are Chromaggus and Nefarian (but they are in the 'meh' category too), if we didn't count Emperor. I have most of the non-Legendary cards, maybe some rare cards needed.

- The other option is that I buy three Get in here pack and I save up in-game money to Blackrock in the cost of 28 pack. The pity timer is about halfway in each set.

Which option is better? Suggestions?

(Sorry for the English, I've tried my best)

Just don't spend the money

 get the packs I am not sure if its a timed event but if it is it might be more usefull to get more cards also it should take you about a week to get enough gold for each wing so you can take your time  

I would go for the 3x Get in here packs if I have Emperor Thaurissan already, since they are a great value packs (but don't expect anything too crazy out of them - just a lot of normal/rares (usually dust) and maybe some epics). You can buy the adventure later with gold.

If I don't have the Emperor - I would go for the adventure, since this card is like the Lich king - it can be put in almost any deck, you don't need to build the deck specifically around it and it has value immediately after played. I love this card. 

I've bought the Get in here packs and I've opened two golden Legendaries and some good epics too, so it's totally worth it :D

Thank you for the answers!

Congratulations. You are definitely luckier then most, as multiple golden legendaries is not the norm. To be safe I would have gone with blackrock but since you already have the first wing you can purchase the rest with gold! ^^
