I have a hunter but it doesn't matter. The key is getting them down before they get empowered. Once empowered they put up a 50K shield and spell reflects and all sorts of nasty stuff. Pretty much game over at that point.

You know the fast damage macro you made for your DPS to get the bone spikes down vs Marrowgar? I just used the same thing but inserted "/tar adhe" in them. Nice thing about this is that you can spam it while targeting other things with your tank. I have found that a well-timed Capt. America shield works wonders for the adds while killing the adherants.
