More in dept look.
Blood Blood's supposed to be the pve dps tree, and honestly, a lot of the talents in there seem weird for the purpose. >_>
Of course this is an alpha and we only have a small part of the puzzle (no core abilities as mentionned earlier), so this is all speculation, but here's what the talents are telling me.
Butcher - Good leveling ability. Might not be that good at level cap depending on how important the reduction of Runic Power lost is.
Blood Aura - No brainer, must have ability. This is the DK's group dps buff.
Improved Blood Strike - Not knowing how important Blood Strike is, it's hard to put a value on this. Either awesome or terrible, depending on the value of blood strike and how easy/hard it is to put disease on a target.
Blade Armor - Despite having no shield, it's easy to assume plate armor will give around 10k Armor at level 80. That's +200atk power. Pretty solid.
Deflection - Parry? >_> It's low enough in the Tree that a Frost DK can go pick it up, but it seems like an odd choice anyway...
Rune Tap - 300 Health seems weak, especially when you consider the new level 80 cap. I'm assuming however, that they'll be several rank to this ability. Sounds like your typical solid 11 point talent.
Dark Conviction - +crit % is a no brainer for any melee dps. A shame it's this deep in the talent tree (Warrior, Rogues and Hunter's similar talent are first Tier in).
Subversion - Increase crit on core ability and reduced threat sound solid.
Improved Rune Tap - This depend on how powerful Rune Tap is to being with. Since this is a pve dps tree however, you probably shouldn't be taking damage in the first place. Might be good for soloing.
Spell Deflection - Er... what is this doing in a dps tree? It's getting pretty deep for a tank to grab it as well, but still possible.
Vendetta - Great grinding/leveling talent, pretty much useless otherwise. Surprisingly high in the talent tree. Sadly it's a pre-req for blood mark :(
Scent of Blood - Typical 'You crit me, I kill you!' talent. Good for pvp and grinding/leveling, not so much for pve dps. Pretty high in the tree, if you want this, you cannot get the 51 point talent in another tree.
Blade Barrier - More increased parry, this time to high in the tree for a 51 Frost DK to get it... seems kinda dumb to even be there.
Mark of Blood - Sounds like an awesome ability all around like any 21 point talent should be. Put this on the MT in a raid and watch the melee group be kept top off with no effort. Could also be used in pvp if put on the focus target or flag carrier or what not.
Bloody Vengeance - Stacking melee self-buff. Seems solid.
Pestilence - Sounds fun and unique if nothing else. I predict this being awesome for all type of 'lawlpvp' (world pvp, BGs, etc) as well as grinding/leveling, but rather useless in more 'professional' settings (Arena and Raids).
Hysteria - The Melee Power Infusion. Sounds like a powerful ability and possibly a chief reason to bring a Blood DK to your raid. The earlier Mark of Blood ability should more or less cover the damage caused by this. Has the potential of being extremely powerful depending on how long the cooldown is (Who's to say it's in minutes...)
Veteran of the Third War - Well, it's boring, but you can't really complain about it. Sounds solid.
Sudden Death - Gives one of your core ability a chance to make another core ability be free. Seems quite solid for sustained dps, similar to Relentless Strike in concept.
Blood Rune Mastery - Another solid sustained dps ability, making me think of Combat Potency in concept. Again it depends on how easy/hard it is to disease a target. Note that this mean your Rune regenerate faster, making the already dubious Blade Barrier seem even weaker.
At this point I'd like to note that Blizz is obviously not interested in repeating the 'You need 20 point in Assination for any build' rogue mentality... all the 'sustainted dps' talent are pretty high in the tree.
Will of the Necropolis - Uh? And the point of this is? I suppose it kinda plays off Blade Armor earlier, but even a 15% increase Armor isn't that impressive of an AP conversion. Seems rather dumb. After all, as a melee dps, you shouldn't be taking enough damage to make this worthwhile.
Vicious Strike - Pretty typical dps abilities, every class has something like that. Once again it's shocking to see it so high in the tree.
Heart Strike - DK's Mortal Strike? A bit weary here, since it seems similar in concept to Envenom, and in most case, removing the poisons (disease here) for damage was simply not worth the trade off.
Blood Gorged - Now you're talking! With Rune Tap and Mark of Blood and not playing like an idiot, you should be at over 75% health pretty much at all time in raids and 5 man. This translate in a near permanent +15% dmg. Will probably suck for leveling/grinding/pvp however.
Dancing Runeblade - At the very least, this doubles your damage for a short period of time... and at best, it might be usable against a different target then yours, opponing some interesting strategy. Seems very solid. Again, the power of this ability will be closely linked to its cooldown.
