Either way, I want to experience something new. Not something old with better loot. Plus, as Phaelia at Resto4Life pointed out, the better loot may not be worth the public humiliation.
What do you think? Are you happy to revisit a classic World of Warcraft themed dungeon like Zul'Aman, which, despite its looks, has new mechanics and bosses or are you yearning for something new like Sunwell Plateau?
