Basically, what ele used to be, the turret-like glass cannon that if you let the shaman alone he would global everything has basically transformed into an unstoppable glass cannon that will global anything no matter what.
TL;DR Lava Surge procs + instant LvBs + mastery procs = insane unstoppable instant damage you can't do anything about.
