WHM don't have fairies, or Aetherflow. Our stoneskin is inefficient and takes too long to cast to be useful during a fight other than refreshing on a non-tank, if there's time. We have Shroud but its cooldown is 2 minutes. WHM have no way to mitigate damage and have to be careful to not overheal because the aggro is ridiculous.

You have to consider that a SCH is not just a SCH, but a SCH + a fairy. Neither class is "OP." They're just different.

I agree with the first two posts. SCH accomplishes the same thing as WHM through different methods. What needs to change is the player's approach to using those methods if they are not successful with them.
