Have had the same problem with Queen Pen and stars. Took me 872 blue stars to get her from 8 to 9 stars.
One of two things are happening. 1. Either there is a window of opportunity to get certain heroes to star and saint. or
2. There's a glitch with your hero.

Expecting Tynon to fix it will be your biggest problem though so just keep trying. Good Luck.

Hello all,

My Herja is AA4 with 12 stars and I am having a problem getting her AA5, her max. I have used 15 cards in 3 sets of 5 each getting to 80% and have all failed. Has anyone else had this occur to them or is it just my dumbazz luck. Appreciate any feedback. Thanks.
