Everything is stupidly easy

Q u o t e:
WoW is currently on easy mode. Blizz, you better have something up your sleeves with Wrath because I don't feel challenged at all.

Bear in mind that most class changes made in 3.0.2 have been much more finely tuned for level 80 content than level 70 content. Some quick adjustments to PvE content were made at the 70 level to ensure the content is doable and relatively user-friendly as the Burning Crusade winds down. In Wrath of the Lich King you'll find much more carefully considered tuning of encounters and class abilities.

Now is a good time to test out the changes made to your class before you hit the shores of Northrend in November.
