Out of the entire expansion, the only zone that has felt the slightest bit team-favored has been Twilight Highlands. Every single other zone was collection quest madness. I don't know if it's to retard the leveling curve or what but it really did get old. I thought WotLK was bad but Cata was so much worse. Bad enough that I'm having a very hard time getting motivated enough to level a second 80 team to 85.
