I saw a 70 shaman using Stormstrike with a 2h mace. Anyone know how?

70 male troll enh shaman using Hammer of the Naaru w/ agi-crit gems in it, xmogged into s1 gladiator mace. I don't remember his name, but he was SSing with it. I asked how he did it, and someone else said "it's a macro". Any idea what it is? He had the 2h out the entire time, there was no weapon swap. His SS were also hitting haaard af, it was definitely regersting the 2h as a damage base. I've received skepticism on other forums, but i'm 100% sure of what i saw. I already browsed through the exploit forums and didn't find anything related.

Stormstrike doesn't require an offhand weapon, you can use it with a 2H weapon all day. Lava Lash is what you need an offhand weapon to use.
