Drop issue

[TheOnlyYetti_PSN]

Is anyone else having a drop issue with diamonds quests. Then last 2 nights I have done 10 rounds of DQ and received the drop 3 times. I play on ball of fame and it has ranged from 82 percent pull change to 37 percent. I feel it has been terrible. Did the Troy glaus one last night . 5 stadiums and did not receive the reward once!
