If none of you read my thread about Spell Reflect on Anub'arak then you probably haven't tried this yet. During the second phase of Siamet in The Lost City of the Tol'vir he will randomly absorb nearby stormclouds causing him to do a mass amount of damage to every party member. If you're a warrior tanking (or have a shield onf or w/e reason.) you can Spell Reflect for the ENTIRE duration of your spell reflect buff. It will reflect the 2300 damage he does a second to him while your spell reflect is up and not consume your buff.
