I know this is up to the people who enter the matches but I've been keeping an eye on my ranking since I did well in there, hoping it would push me into the Top 100 and retroactively take away my inactivity decay but the first matches were 3 weeks ago and it's still not entered. So I wanted to ask how come? If it's because it's the Challenger division then why did Season 4 have its Challenger games entered?
