yeah that UI is cool.  It's hard to watch because you can't tell what he's casting most of the time...when it's not chain lightning, lightning or shocking (which he only does about 15-20k damage each fight)  he's purging the crap out of stuff and trying to stay alive.  His pally heals the shit out of his team and the priest does a bit too.  I need to watch it a few more times.   I definitely need to put purge on some sort of macro so it purges our assist without me needeing to switch targets.  Do you know if I can have a focus for my shocks to interrupt and another focus or an assist macro for who we're killing to purge without losing my target?  (his warrior does a ton of dps too.)  I also noticed he seldom has grounding totem down either, at least agains that team)

Anyhow, gotta go to school.
