This is my basic BWB DK. Some skills and passives will not be available as you lvl up but you can see the direction I go with each skill line. By lvl 30-35 you should be able to achieve most skills and passives.

Gear is Krags or Alchemist for the heavy 5 pc. Reinforced on the big pcs, and infused on the small pcs. Light for the other two pcs with infused as the enchant.

Jewelry...lots of room to work here. Lots of options. I usualy pick something that will add a max mag, and spell dmg. Then I put spell damage glyphs on all 3 pcs.

Sheild charge as a gap closer until you can open chains...thanks zos... or no gap closer, just use leap to close that gap.

Purge is awesome but takes a while to get, until then I will run Obsidian shards or Annulment for a bit of a shield.
