It's really no different than 2.0 release, we don't have the extra piety, our heals are less powerful and everybody takes more damage. All these issues will be alleviated as we get higher tier raid gear. I like the fact that I can't just afk spam heal through the new instances. If you compare apples to apples (i70 in 2.0 vs i180 in 3.0) the proportional cost of mp use vs total mp is pretty similar.
