I like the idea of using the ECR rate to limit bonus pack rewards... you can do an average for the whole season (to penalize ridiculous number of games as you suggested). For instance, if you averaged an ECR rate below 70% for the whole season then you aren't qualified for the season packs. I have played since the beginning and don't know any human that averages below 70%.... of course people can dip at the end of the season but 70% ECR is running your account pretty hard. Good idea imo
