If interrupting it locks out the Frost school, I'd probably just omit it entirely from the rotation.
That would be no Howling Blast or Obliterate, which are the main attacks in the two rotations; for that matter, that is also no Death Strikes.

DK Runes aren't really schools of magic, so I don't see them locking a rune out based on the interrupt.
