There was nothing wrong, A 0.1% X 3 = 0.3% it's still minimal. 3‰ means 3 in 1000. But that resets per each fight. It doesn't increase the more you fight. It's a dice roll to basicly roll 1000 6's in a row. Anyway, it's complete rng and people that didn't obtain the girls are just mad duo their lack of luck. No compensation
