Something Diabolical - Fizzcrank - US
Lastnight we killed Freya +3(10m) zerg style. She had 150 stacks of Attuned to Nature.
Here's the video of the kill. http://www.youtube.com/watch?v=PuvKiJsG9Mo
(if this wasn't world first sorry but I couldn't find anything anywhere saying someone else has done this)
