Anub-arak so far has been great fun
My favourite boss in Naxx was Heigan it was always great watching my guildies die to the dance.
I am a fan of Noth
Thaddius is my favorite boss! I'm a sucker for creepy stories and general spookiness, and the screams in the background during the raid up until him create the best atmosphere for the already unsettling instance.
Heigan definitely. Usually only 3 people survived and killed him. The dance was amazing!
Best boss so far has to be Heroic Maexxna. Definitely what I imagined a Hearthstone puzzle mode might look like!
Always loved Thaddius, especially the jump from Stalagg/Feugen onto his platform and seeing atleast 3-5 /40 fall down. Plus i loved his Polarity Shift mechanic, such a unique and awesome bossfight.
i love Maexxna for returning all my battlecries back into my hand :D
Had to be Loatheb. Just because of the amount of time it took to actually get his Achievement.
I like Grand Widow Faerlina, especially when you kill the worshipers, they failed her.
My Favourite boss is gotta be Heigan. He has given me and my mates some good laughs with all the Dance-failing :D
Favorite Naxxaramas boss? Kel'Thuzad of curse!
My favorite boss in Naxxramas is Heigan, mostly because my raid-mates weren't able to complete the safety dance.
Always loved the four horsemen boss fight in Naxx so hands down they are my favorite.
Heigan, love the dance.
Noth the Plaguebringer brings back fond memories of wow with this card :)
Totally Heigan. Always had to blast Safety Dance during his fight.
Really enjoyed Grand Widow Faerlina on Heroic, forced me to play my rush deck :)
Heroic Maexnna :D
