Your Duel Class Crystals Are a Ripoff and need be adjusted!
Everytime I've attempted to get a decent champ from ANY of Duel Class crystals I have gotten same duplicate champs I already have!   We don't open a Skill/Mutant crystal to get a Winter Soldier, Black Panther Classic, Bishop or Cyclops Blue Team for 4th time!   I just opened a Tech/Cosmic Duel Crystal and I got Howard The Duck which I have already had level 80!   I have at least 50 possible Tech OR Cosmics I didnt have and at least 5 that need awakened and you give me a trash champ I already have !   You could easily make the algorithm lower chances to get a champ that is already awakened!   Last 2 Science/Mystic Duel Crystal's I got CLASSIC Captain America and Iron Fist?!?! SERIOUSLY champs from games beginnings should be filtered out these crystals and kept in classic crystals.   Tired of saving for nothing!
