Just do practice arena...If you're doing ranked no one queues yet because it's not cross server. Practice/Training Battle = same as old one. Ranked will have you waiting forever.

Plus you know you can hit "escape" and close the arena page but stay in queue? So you'll be pulled into a match in middle of w.e you're doing when it's ready. Helpful and wish I knew that when I first got Six Path Sage rank xD
