For most part (shannox dog, Beth'Tilac or Drones, Lord Rhy Spark of Of Lord Rhy and the Hatchlings) I find myself using the Alchemy Trinket along with the DPS reward from Avengers of Hyjal Revered (the 383 Mastery and On use + STR - Spidersilk Spindle hasnt dropped yet) because of the awesome block.. For Baleroc I use the Dodge one from AoHyjal and the Moonwell Phial for the dodge CD.
Even though I am a warrior, our mechanics are similar.
