How exactly did you prove that this increased your DPS more than walahra turban, and how much haste did you have stacked in those tests? Because ordinarily I would say there would be no way 3 attack would be better than 1% haste
Finally useful until you can get Brisk Mask for a MNK's footwork build. Since with Haidate, Poise, and BBelt, you're capping haste with 4 haste, you may as well get the 3 ATK from this!
