Instance: Halls of Stone
Box: Protection Warrior(epic gear), Resto Druid(crap gear), Arcane Mage(+- 10 epics), Elemental Shaman(+-10 epics?), Survival Hunter(a few epics).
Difficulty: medium to hard

Krystallus
Put your characters in front of the rocks so they don't get pushed back. The shatter seems so large that the rock formation at the left is too close to the second left rock formation. Try putting your left-most character as far away from the second-left rock formation as possible. I'll try to take a screenshot later to explain this more clear.

Maiden of Grief
Put all characters on the stairs and tank in front of them so that the Storm of Grief spawns only where the tank stands, away from the rest of the group. The tank runs 20-30 yards in front of the rest of the group from left-to right. He moves every time Storm of Grief is cast.
This means your healer will get stunned and can't cast for 10 seconds. That means it's important to always have a HoT(healing over time) on your tank. This fight is easy that way, especially with a Druid healer.
I will post a video of this later.

Tribunal of Ages
This is where I fail for now. The biggest problem at the moment is the laser beam, because it comes at a point where my tank is getting swarmed with adds.
