question about the player pool and hero crystal pull
dear kabam
My question is when a player pull a champ from any hero crystal, what determines what class of champion that has a higher percentage they will get?, "example player A opens a 4star crystal and has 60% chance to get tech and 10% chance to get skill, and player B has 60% chance to get skill and 10% chance to get tech" I know that the player pool is broken up into tier "low, middle, and high" is each tier has a set percentage of what class of champion that a player will get more of?
The reason why that I want to know is that out of my 50 4star champ that I got I pulled only 4 mutant so be for I open another 4star crystal PLZ tell me why.
