Soz for my english.
With the 4.0.1 patch you can dispell your mates without a magic on them.
With the [Dispell Magic Glyph] you heal a 3% of the target hp every dispell.
If you dispell Valithria on the encounter, you heal for 360ks. 33 dispells and finish the encounter, its takes about 35 seconds.
I used the search engine but dont find nothing like this.
