0:30 You should have ghost wolfed away from the DK instantly when he gripped you.
1:05 you tried to ground the mind freeze but there was just too much stuff being casted on you = no way you could have gotten the mind freeze with grounding. Also you paniced and tried to trinket the interrupt which just doesn't work
1:40 You tried to go offensive with the hex, but you didn't even have your earth shield on anymore. Also while you were casting the hex, the shadow priest was casting a 30k mind blast on you, that was just asking to be killed.
In general you need to be more careful, use ghost wolf more to get you in a safe position. Those are some things that I noticed
