I don't know if it's good to revive such an old topic or to just make a new one but here goes.
On Feng the Accursed, you can Ice Block off "Arcane Resonance".
You can Blink through the flanking Mogu statues, on the Spirit Kings. You can also blink out of Pinned Arrow.
On Elegon, you can stand just at the edge of the dome and when you get the stacking "Overcharged" debuff, you can just jump with an instant cast or when refreshing your Mage Bomb instead of moving back and forth.
I will fire up a new tips/tricks thread tonight and sticky it. Please feel free to re-post this there as well.
