Looks like North America will be pretty competitive. In less than 12 hours, 680 people have attempted an event and the #256 cutoff is 6 points. There's still a lot of people who are waiting for the meta to settle before they begin attempts.
If you want to qualify, you'll have to use all 50 keys. It helps to win games too.
For comparison (timezones slow some of them down)
>Europe #256 - 0 points>Latin America #256 - 1 point>Oceania - 38 participants, so #128 doesn't exist yet>>44960150I think it's any region so you should play in your own region's peak times. It's not enough to win, you need to make sure your competition gets fewer points.
