I really like the changes this way, just would love to see some more variations in the Quests. Would love to see some different difficulties. For example a easy quest could be upgrade some cards. If you have saved gold you can do this mission in some seconds, else you have to farm. A hard quest could be doing a special mission on high difficulty, which still could be rerolled but with a lot of thoughts and a good deck can be handeled in more than one hour. This way you give players a reason to spend more than one hour in the game, while still feeling a little more rewarded. Moreover i would love to see some number/dmg/life tweaks to some rare used cards, to give us a reason to try new decks instead the common used decks. Number tweaks shouldn't take to long to implement and could be reverted fast. Some ideas from my side, keep the good work up!
