Do you have any sources to indicate that the % were nerfed, or is it just the typical "I didn't receive the reward, thus it's rigged" ? Would love to know the sources from your statement.
Judging from the players perspective, quite a large number of people obtaining the ninjas, and heck even doubles from the same person. But regardless of what I say, you have your mindset on your opinion. Just like the group wheel statement right?
But seriously, those sources would be great. https://media.giphy.com/media/J5nvj5lh8kgGk/giphy.gif
