Map pool is posted!
I have also added a poll asking if people would prefer a U1500 and U1000 section be created for future seasonal invitationals. I would create separate brackets that would just be for people under U1500 and U1000 ladder. These brackets would just be playing for avatars and wouldn't be part of the main tournament.
This qualifier is the first time there's been significant interest from the U1500 crowd. It wouldn't be a large amount of additional overhead to run separate brackets if people prefer that.
