Frost DK macro, need help

[Ualaa]

I'm using a priority sequence with IS Boxer.
Essentially mashing a bunch of keys.

I haven't really looked if this is entirely optimal, but am boosting 1-80th, with an 85th so it will work.

#1

/cast Howling Blast
/startattack
/use 6
/use 10

#2
Frost Strike

#3
Plague Strike

#4 (Can toggle this one off)
Death Coil
