Please flag someone as "did a battle" when he's been in the queue of live arena for > 5min. I've had so many weeks degrading rank by just being unable to find someone.
To get people ranked up a bit and enticing people to join: maybe give 10 ranking points/minute that you're in the queue too?
Note in case people will code it without thinking: if you implement this 2nd part, kick everyone out of the queue when live arena closes...
