Straight, no fuzz.
one big chunk of boss standing there, shooting a fireball at some silly peep every once in a while, and all you do is deal him straight down.
fun because it was the first boss i could measure dps on, as no other things needed to be done.
for now, i enjoy VERY much Thaddius in naxx.... precision running + UBER damage buffs + one guy runs wrong, the whole raid wipes.....
Come and join on Starcraft 2 as well =]
