Hearthpwn

Am I the only one who is super disappointed? I love hearthstone and have invested so much time and money into it over the years. I loved all 4 solo adventures and from what I recall it went packs-adventure-packs-adventure repeat but now it seems like we only get packs and we cant buy the £20 adventure and unlock all the cards as we complete it. I dont have a lot of money anymore or not as much as I had so I cant invest into all of these new card packs and get the cards needed to climb and have fun. I have plenty for GvG GTG and WOTLG but these newer expansions are getting on my nerves as the cards I have are being rotated out and I cant enjoy the game I once loved. I know you get rewarded for playing these missions but it is still going to cost an arm and a leg to get every card :/ 

Hope im not the only one who feels like they are being forced to stop playing due to not having hundreds and hundreds of pounds to spend on new cards
