Hey i was looking for a macro which could do a castsequence, with the spells Nether Tempest and Fire Blast.

At the moment i have
/castsequence Nether Tempest, Fire Blast, Fire Blast

but i want a macro where, if Nether Tempest is applied it uses Fire Blast, and if Nether Tempest is not applied Nether Tempest is use rather then Fire Blast.

Cheers
