Summary: normally only 1% of the players will win, but if you have never won in that Season (usually 10 weeks per Season) you just need to finish in the top 10%. This way people who don’t win get better odds of winning as time goes by.
1). We will keep a list of every player that has won a grand prize in a mission
2). The list will be wiped out every 10 weeks (number may change based on feedback). We will refer to this period as a Season.
3) If you have NOT won a grand prize through finishing in the top during a Season, then you are placed in pool A.
4) If you have won a grand prize through finishing in the top during a Season, then you are immediately placed in pool B.
5) For players in pool A, the number of grand prizes awarded in each mission will equal to 10% of the people who completed (everyone in both pools who got to the end including the people who lost) the prior week’s mission .
6) For players in pool B, the number of grand prizes awarded in each mission will equal to 1% of the people who completed (everyone in both pools who got to the end including the people who lost) the prior week’s mission.
Because everybody is back in Pool A, now, the 10% number is higher than it has been for the previous few weeks. This means you have more of a chance to get it, but it also means that it will “run out” faster than it has the past few weeks, due to the majority of ‘very’ active users now being back in Pool A.
Well considering the last OM had wind arks I doubt they would hae those again. My guess is earth bc when the ark was water type the mission arks were wind. So now that the reward is wind the arks might be earth
But everyone is now in pool A so 
Many ppl can and will get it
