I like it too, even If I know that Dalaran Heist is similar to Dungeon Run (8 bosses out of xx), it feels kinda nice and relaxing to do it. I gave up on Rastakhan's Rumble adventure, but in this one I am going to complete all chapters with all heroes and both anomaly and heroic modes
I love it, it's fun to play and very replayable. Maybe a little bit easy, but nothing too bad.
My only problem with this adventure is that I have played Thronebreaker (a single player adventure for Gwent) and the comparison HURTS. 30 hours of solo content with a great story and characters, tons of rewards and cards for the main game... and it's 30 euros.
