It seems like they do try to do away with Heronium farms. If I recall right, they said that is part of the reason they changed up the way the stores were handled. PVP use to have 10 heros, that never changed. Then they changed it that all 10 heroes change every month, and now they only keep 2 the same.
Also, they only kept Salvatore as the 13/13 daily quest prize for about 9 months. Cinder has been there way longer. If nothing else, I would like to see them put someone else there, and I have Cinder at 10*. Hopefully a chance to build another hero that I may not have focused on previously.
