Am I the only one who thinks there should be a duelling area on the fleet? Or is there already a duelling area that I'm just unaware of? (will it be in 1.2?)

If you played WoW you'll know that that's what people used to do at the Gates of Ironforge; there were always duels going on and anyone could participate. Based on that experience, I think duels can be fun thing to do while waiting for your warzone queue or flashpoint group, and it's good practice if you want to master your class.
