Having gear levels a *lot* closer between the classes atm is helping to stop the outgearing face rolls, so now's probably the best time to get a feel for true balance. From what i've seen so far though, we're still not great against people who really know their class so i have a feeling it's not going to be a great season for us again.
One thing I am loving though is shamanistic rage; not for the dmg reduction, but because of it's glyphed effect. The amount of damage you can negate with it is truly godly and it's saved my hide more times than I can remember. As for our damage improvements, I would say they're mediocre at best, lightning bolt still hits worse than a holy pala's denounce and takes longer to cast. Having said that, it seems to scale very nicely as in Pve gear it's critting for almost as much as my LvB so it may be quite good in tyrannical.
Healing's definitely much much better now, especially as you can always guarantee a boost with LvB->clear casting.
