Yeah, as a warlock I use sacrificial pact when I know I'm going to be taking damage. Works in raids too, while I'm in midair flying into the stands during kargath, I pop the shield so I can nab agro on some of the further ogres/bombers and not take damage. They tend to target the tank on kargath or Skrigg from the get go. Shield butcher's bounding cleave when I can, crystalline burst on Tectus etc.
For me it's about 110k shield on a 1 min cd (based on pet health if you have one or takes yours and creates a shield if not).
Also use shadowfury to AE stun packs (CMs, Kargath stadium etc).
Command demon for Terrorguard has an interrupt (went about 5-6 heroics before realizing this).
Soulstone can be reactively used on a dead target (no idea how long this has been true, always had to precast before).
