Chance of opening 5* feature champion
Please correct me if I am wrong. I understand when I open a 15k 5* feature crystal, there are 3 pools of champs to choose from. 1. feature champ with 25% success rate. 2. sub-feature pool with all previous feature champs in it. 3. basic pool. Based on the above assumptions. What are the chances of getting a champ from sub-feature and basic pools? If a ex-feature champ is being released into the basic pool, does this mean that this champ would be moved from the sub-feature pool to basic pool, or I would have more chance of getting this champ from both sub-feature and basic pools?
