I think blizzard have started nerfing quests already..

whilst running my latest mixed group through Nagrand I noticed that the Nessingway kill quests are only 12 of each now rather than 30, the Boulderfist mage and warrior kill quest cut from 20 to 10 and the telari supply crates collection quest has been halved from 20 to 10.. there are probalbly lots more thay have changed, but those are the only three i really noticed
