Crit when you want [Shaman]

Thanks to http://www.hiddenstuff.com/ for info!

So i was questing in Hellfire and just noticed that if you spam the [Elemental Mastery] and the [Chain Lightning] button at the same time you crit so i used this and critted all the time dident get the cooldown on the [Elemental Mastery] if your doing it right and be fast enough so good luck and have fun critting
