yeh could turn
Icy Touch --> Plague Strike --> Pestilence --> Blood Boil --> Death Strike --> Death Coil --> Death Strike --> Blood Boil --> Blood Boil --> Death Strike --> Death Coil --> Death Strike --> Blood Boil --> Blood Boil

into
Code:
/castrandom Death Coil
/castsequence Icy Touch, Plague Strike,Pestilence ,Blood Boil , Death Strike , Death Strike ,Blood Boil , Blood Boil , Death Strike , Death Strike , Blood Boil, Blood Boil
put that on one key
then create another cast sequence for yer other chars on the same key
that way what yeh could do is initially click on the key to get aggro then just mash the button for everyone to start dpsing
