In this patch, DK damage in both Unholy and Frost was brought down significantly in more ways than one wow gold. Frost saw Frost Strike base damage nerfs, the ability to dodge it, and sigil nerfs while Unholy saw base scourge strike damage and disease scaling nerfs, desecration 5% damage loss, as well as a much easier to kill gargoyle about wow gold. Although some of these nerfs were definitely necessary (such as the XT sigil), some were also completely overboard and just resulted in a really bloated unholy tree. I am mainly referring to the desecration change where they split that talent into the new desecration about wow gold (2pt pvp talent for just the snare) and the new "Desolation" (5pt talent for 1% damage per point after blood striking). They could have at least just made it "increases your damage by 1/2/3/4/5%" and it would still be a dumb talent but they found a way to make it even worse, cool.

In any case, Blizzard really does not understand the true problems right now with Death Knights and there are 2 in particular that stand out to me the most:

Endless Winter - the ability to apply frost fever (and ebon plague if you are unholy) after doing your main snare ability about wow gold (chains of ice) is pretty overpowered and the fact that the diseases are a different dispel type from the chains of ice just makes matters worse. Like most classes, a DK should have to make the decision on whether they want to use their resources offensively or defensively, not both.

Chains of Ice - I think the ideal fix for CoI right now is to give it diminishing returns when applied on a target already affected by chains of ice about wow gold. This would keep it as a useful snare still while fixing the problem of CoI spamming to completely shut a team down with or without dispels.

Fix those 2 problems and the hero class is not so heroic anymore, but like anyone else. Maybe then Blizzard will realize some other glaring problems that exist right now.
