Just watched your vid, very smooth kill. I remember doing it with the same setup as you and its a tough fight with the nature resist. Although once you get it down its quite easy. I ran it 3 time from memory and on the 3rd I was setting up my totems and group position and accidently pulled her before I was ready, still managed to get her down

Question for you, I love information on my UI, what is that graph your running? is it for threat?
