3% Hit > Agi > Crit > Hit > Haste
That's the stat priority if you're dual wielding. Obviously if you're using a 2H any hit beyond 3% is redundant.
Edit: In light to your comparison with rogues, haste is actually a pretty decent stat for WW monks. Whereas most rogues forego the BoA pants, monks should use them instead of Smelting Pants.
