Ever since the Death Knight class was announced as a hero class, information about the class was always sought after. When the first set of information about the class was released a while back, it painted a picture of a class that is different what what we've seen in the past with the runes and runic power system, the spell damage tanking niche, disease based spells and many more.
I've heard that the talent trees were lurking around the internet a few days ago but I never really went out to look for them. but after I read a few interesting things about the trees, finally I decided to look. After some looking, I decided that the most complete and best presented on can be found here at Warpirate, which is a web site you can use to make your own talent trees. Someone made one for the DK talents that was going around. So for those looking for the talent trees, finally you found them!
What's very clear to me based on the talent trees is that no matter what spec you are, it's always important to keep your targets diseased because each tree has something to increase your Death Knight's effectiveness against diseased targets.
Based on the talents as they are now (since we know that we'll defiantly see a lot of tweaking from now until release), I can say that the Death Knight will be a fun and interesting class not play!
Just in case the link above from Warpirate disappears for any reason, the blood, frost and unholy talents of the death knight class can be seen at Blizplanet, although some of the slots are not filled up.
