So let me just be the first to say that I am in love with patch 2.3. I really like the UI changes, although none of my add-ons work anymore. The track feature is really nice, and being a leatherworker I immediately made a 20-slot ammo pouch (24 soon to follow). I'm in love with this new ammo pouch... it's awesome!
Also, as big a proponent as I was/am for keeping the dead-zone, I do have to say it's fun to have a frost mage blink into my face and then eat a nice big mouthful of arcane shot. =P
