DH is my alt and this isn’t about me. If you think Fury has good defensives then I don’t know what game you’re playing. We only have Enraged Regeneration which sucks a$$. DKs have AMS/AMZ which negates most dmg as most dmg in the game is magic dmg. If that’s not enough you have so much healing with Death Strike.
I play TSG and when they target my DK buddy he can stay alive for a very long time. Next time you fight a Fury just try training him. If you don’t just outright kill him, you will at least force him to play defensive.
