So lately I've come to realize most of the times I've beaten a DK was because I had help from my partner. In a 1v1 situation, I'm completely lost and feel helpless against DK and their huge amounts of damage that seems to come out of no where. What are the specific cooldowns I should look out for? I know theres IB and Desecrated Ground, but that's it and I think there are more? Most of the trouble comes across UH DKs, while good Frost DKs are very much a challenge as well.
