I haven't got single mystic or tech champion till now

I have opened 20 4 star crystals and one 5 star crystals till now. But I never got a mystic or tech class champion. I know this is really weird. Is there any body like me who have never got a 4 star mystic or tech champion

You're still at the beginning... That is still a small amount of crystals opened
