The Ironworks chest and legs are easily the best pieces for NIN in the game. Avoid purchasing the head, wrist, and earrings. The rest of the pieces are pretty good filler until you get your hands on Dreadwyrm or crafted i110 (with maximized melds). Also, skill speed is pretty much a stat you want to avoid in most cases. Stack Determination and Crit while trying to reach an accuracy amount of 535.

Head is actually crucial to reaching the 441 Skillspeed point that lets you get an extra GCD inside every trick attack. So much worth.
