Cheers, since strangulate is a 2min CD how do you suggest I manage it?

The only way I can see it going in the cast sequence is if it goes in

DK1
/castsequence reset=target Chains of Ice, Howling Blast, Howling Blast, Strangulate

Since this will only have an 8 second window (in own suggested change) to get through the sequence + frost strikes
