[Guardian]Appreciate any tips for Durumu 10N :)

Hey fellow bears, kitties, chickens and trees :)

I'm gonna help a friend's guild tonight tanking ToT on my bear. He is my alt and is a bit undergeared (500 ish?) with T14 4-set. While I don't suppose other bosses will be a problem, I do somewhat worry about Durumu. Is there any helpful tricks about tanking this boss as bear?

Thank you very much!
