If it is your first time using seal scrolls in kage, how much seal scrolls did you use to get Killer bee out of the 100 you used? Like you said, the average is 60-70 for one rare. However, if you somehow managed to get bee below the average (below 30) and tried to pull for a second rare based on the average and it added up to 100, I can see why you would be upset.

Was it within the 2 weeks after 3.0? There were a lot of people reported abnormal pull rates in kage. After that, it seems like no reports for the 3rd week
