Basically, the blood tree gives you some personal dps talents that also give personal and group heals based on the damage you do. It also has a talent rune tap that is sort of like a healthstone, but cannot be shared and uses one of your blood rune charges. Almost everybody in beta is using this tree to level because of rune tap, blood aura, and blood worms, which provide quite a bit of heals.

The frost tree is more of the tanking tree and also has the abilities that allow death knights to kite mobs and cc. It has talents that reduce party and raid damage and also increase party resistance. It also has talents that reduce mob movement, attack and casting speed as well as talents that increase armor and parry.

The unholy tree is my personal favorite and the one I have been playing. It has talents that increase damage of the diseases and also add things like +13% damage to spells to the mob with the disease and an anti magic field. Unholy also turns the 2min ghoul into a pet that you keep till death. I expect the best overall raid dps from this tree.

All in all DK is fun but vastly unbalanced right now. It's disgusting to have seen all DK instance runs because of the massive group heals from dps. It was also annoying to have people running around with 30 ghouls at once. I expect it will be a really good class but considering my play experience with it i'm wondering how raid synergy is going to be affected by DK's. I'm not so sure that tanking is what they should be in the raid for. I am thinking that the support abilities blood and unholy trees bring are going to be more in demand.
