This has been another mistake found in the FFXI English client translation for armor descriptions on the new gear.
This head does in fact give 3% Haste.
If you'd like a quick view of this mistake using ffxiah.com, look on the left hand side of your screen right under "Donations." There is an option that says "Language: JP EN." Click "JP" and it will show you the correct armor description along with the 3% haste.
@ Sephirothforbes
The set is infact 14% haste total yes; 3/2/2/2 +5SET making this on par haste with the standard homamx3/turban setup for drg/drk, but most of the time more beneficial stat gains.
I understand about the translational error, but how the hell do they screw that up? It's the same arabic based numeral system. 3=3 in both languages. I don't know why they would need write the stats again instead of copy and alter the original dat and leave the original numbers changing only letters, but whatever.
