I'm running a (Nord) vampire stamblade as "main" now. All other aspects aside, I'm using Hulking Draugr and Bone Pirate (Bone Pirate Jewelry, so all gold Draugr), with Nirnhoned Asylum 2H sword and infused Master's Bow (weapon damage enchantment).
Obviously, I'm running two "sustain/resource" sets. I have a Max Stamina of like 43k, and my weapon damage fully buffed is 3900'ish on sword, and 4000'ish on bow when enchantment and caustic arrow procs. My stamina recovery in Cyrodiil is around 2500 when I got the "buff" from capturing keeps etc.
As for my playstyle: Either I go full close combat, and only have buffs, shade, fear etc. on backbar - or I go mainly "bow gank" with Lethal Arrow, Poison Injection and Radiant Magelight etc. I switch between these depending on the "tactical situation" and mood.
It's working pretty well, but I'm a "tweaker" by nature, and would like some kind of more bells'n whistles. I'm a fan of
http://en.uesp.net/wiki/Special:EsoBuildEditor, and have tried some several other builds out there - theoretically. But no matter what I try to use, all-in-all I really don't come close with any other sets. Crap like Eternal Hunt would be a huge deterioration to my build (why are people even using it? That "rune" is a bad joke?), and I have a problem to see that either Morag Tong or Vicecanon would make any big difference. I can see that Spriggan's, Two-Fanged and Automaton/Hunding wouldn't make it better. The one set that seems pretty close, is surprisingly enough Sheer Venom - that's the only one I actually think about trying.
I tried one piece Domihaus, and Bone Pirate 2H sword and Bow, but obviously I want to keep using my "special weapons" for a reason.
I understand a build editor like this one might be a bit difficult to read correctly, that it doesn't really reflect how it
would work - I just see the numbers. So, anyone recognize this problem? Any really good suggestions for gear? And yes, I know a Nord isn't optimal for this, but as I'm running all Infused/Divines gear, the extra toughness is very welcome. My crit is quite low though, around 40% I think so maybe something giving me more crit, as I can't use Shadowy Disguise before
every attack I do?
Also, would Prismatic Enchantment for the sword be a good idea? Seems like everyone is a vampire these days. I'm running Befouled right now, I think. I haven't thought too much of poison or enchantments for the sword.
