As Lore says, it's worth noting that the latest iteration of Kil'jaeden's Cunning is off the GCD, and can be cast during another cast. So, if you're halfway through a Chaos Bolt, and need to move, you can pop KJC without interrupting your Chaos Bolt, and be on your way. It seems from some reports that this is actually not working quite right on the PTR at the moment, but will be soon. What's more, Haunt is now castable while moving, independent of KJC. Lastly, do remember that this is PTR. It's all subject to change and iteration, and if you're worried, go and test it. Provide feedback. Be part of the design process!
