I like the new heroes don't get me wrong but I think the development needs to be more on the side of awakening the heroes we already have. Especially Jasmine, Kong, Zem and Jasper for me. I'm sure there are others that each player wants.
I would be very happy with the box thing and new awakening instead of a new log in hero. Maybe alternate every month. One month new hero, One month box with choice of 2 or 3 previously released hero soul stones and an awakening quest for an existing hero.
