Unenrolling from Games

I think Race / Arena / Hysteria / Frenzy like should have an unenroll option after you have been waiting for 30 mins... idk sometimes its like annoying when they take forever and you like run into the situation where you originally had time to play one but then it takes an hour to fill... idk i think a 30 min cooldown after you click enroll would be a good idea. sin
