Here are my possible PvE and PvP [fun fun] builds using a Sword coupled with Death magic [oh the horror!]
PvE:
8+1+3 Swordsmanship
9+1 Strength
9+1 Tactics
10 Death Magic
Riposte
Deadly Riposte
Sever Artery
Gash
Bonetti's Defense
Shield Stance
Plague Touch
Virulence {E}
Designed to work alongside teammates, you can ditch plague for res if you think your monks really suck...

PvP mode
12+1+3 Swordsmanship
8+1 Strength
10 Death Magic
Seeking Blade
Sever Artery
Gash
Final Thrust
Frenzy
Sprint
Plague Touch / Res Sig
Virulence {E}
The real monster point to this build is that it buries Deep Wound quite readily and generates 11 pips of degen. The idea is to get to the enemy rear lines and wreak havoc cause you don't want your teammates to suffer from Disease. Ah, the enemy has Martyr and/or Draw conditions? Assault the one who's using it with all of the conditions and Final Thrust them into the dirt.
The build is in essence a combination of Disruptor and Damage dealer. It's ability to do damage won't meet the good old blam* that is Eviscerate and Exe. Strike but to augment, it buries multiple degen on top of final Thrust. So it should balance out nicely.
Conditions really shouldn't be a problem. Dodging and Blocking becomes moot with Seeking Blade. If your % is good and you're lucky, you should be able to land at least half your hits using Seeking Blade spammed. I'm not a fan of Wild Blow due to its nature of being stance countering and most foes I fight don't use stances but use enchantments and wards instead... Dodge this? Start bleeding... [and let me land a Virulence on you for extra punishment]
The obvious weaknesses would most definitely be the anti-condition types. Things like Martyr and Draw Conditions would render your target quite healthy. [but the caster is now buried in 5 conditions, 3 of which are degen] To nullify this problem, directly assault the one using the anti-condition spell and let Final Thrust speak for itself. You could replace it with Galrath Slash to conserve Adrenaline in exchange for spike damage.
Hexes we'll leave to our friendly neighborhood monk...
Any ideas for beefing either build? Yay death knight!!
I'd even consider going on a trip down memory lane and go Bloody Duelist using Blood Magic instead, but that's tricky...
edit** I'd consider using Necrotic Traversal or Consume Corpse for pvp as well to deny enemy use of corpses...
