Do you have Paladin in your raid? If you do I would make sure you are picking up Salvation vs Kings or Wisdom. If you do not it might be better for you to drop Tranquil Air on a regular basis.

For my I do not really have a problem with agro so much, for trash I chain cast LB and keep up Flame shock.

Also this may be a dumb question but did you pick up Elemental Precision?
