Pool A or B

I have never got the OM arks through the 10%, but I have gotten Gearwolf through 5 mission eggs. Does that mean I am put in Pool A or B? 

I assume by getting the ark through eggs, you would still be in the 10% pool.

Yep if u get it trough eggs then ur in A if u finish all floors and defeat the boss and get it then well then ur in B

Excuse my lack of knowledge…but what’s the difference between pool A or pool B?
