HA is a joke. They will not fix it because it was never broken in their eyes. It’s meant to frustrate people into buying gems to pull the heroes they want instead of waiting a week for a duplicate s1 hero. The fact I can put in a Victor (I didn’t do that, it’s just an example) but not receive one is ridiculous. If seasonal heroes are NOT in the HA, they should not be allowed to be used for retraining.
Also, fix the ninjas! Nerf, balance, whatever you want to call it, just do it… But not with costumes!
