If you are curious about the unmitigated numbers ele shamans can pull during cooldowns, feel free to check this VoD of my 1st hc gara'jal kill, about 3 weeks ago. It's for the most part a tank and spank fight, and it's prepot/skull banner/blood lust/... right at the start. I don't use unleash lightning glyph and run with elemental blast/echo. The vid is uploaded from my stream, hence why it's not really fraps quality.
