Hrmm.. I just chose to /duel one of my other accounts to set up the macros.

I ran into something interesting though. I turned off the Button Queue and it seems to break the macros for the cast sequence type setup.

Verified it by placing all the spells in the macro on a hot bar..and only the first one will go off.

Edit - I"m putting the order from lognest to shortest recast in my macros...in case that's needed.
