There's an increased exp rate, and drop rate when you quick party, but listening to the global chat people really don't like using it.
I was at the spider caverns for half an hour last night looking for a party. Sat in quick party que for 10, sat in town being declined entry to others parties for 10, sat in my own by myself for 10.
I was in a corresponding channel too
I think one of the problems was more than half the parties were level 40+ and even level 70? Wth. Area is level 31-55 or something. I was level 31.
