I'm looking for an AoE macro for my 3 mages. Preferably for GSE. I tried to make a few but I'm not too successful in making anything but the simplest of macros.

I want to start off casting Flamestrike, then spamming Arcane Explosion 3 or 4 times, and finishing with Frost Nova.

Even one without Frost Nova would be beneficial, just to be able to Flamestrike into an Arcane Explosion spam would be helpful.
