@Asura.Karbuncle HP+45 Enmity+8 makes it a great cure cheat piece. The VIT also increases the amount cured. So it's actually "above" Bahamut's mask only slightly but still.
This is also very awesome for those who like to Pld/Dnc or War/Dnc since curing waltz's are highly dependent on caster's CHR and receiver's VIT and on this piece you get both!
This is in every way better than Bahamut's Mask, which kinda sucks cause it looks like crap. Wish it was the other way around..
And yeah, with 2x March and Haste you only need 15% Haste, which does ***for you if you don't have a haster and two bards. And especially for soloing, you'll want to stack up on Haste and Fast Cast as much as possible, so for every situation in which your haste is below 50% (which is a lot for me, since my LS is undermanned for most things), you're still better off using Turban for Flash.
As someone mentioned before, this is a great cure cheat piece and that alone would be a reason to get it, since curing is one of the major enmity sources and Haste doesn't matter much for it (see http://www.ffxiah.com/item_sets.php?id=152437). With this and some new items it's finally possible to use a full Cure IV cheat without losing much MP and have lots of enmity stacked up. Also perfect piece for any JA used for enmity, especially Rampart for the VIT+11.
@Unicorn.Sedres This does not beat Koenig Schaller or Augmented Champion's Galea for shield skill idle piece. It is purely an enmity macro piece in my opinion, used for cure cheat and amazing for Rampart. Highly desired head piece but I would not idle in it, especially since with the AGI -7 it is actually a negative your shield block rate.
Haste doesnt matter unless you /nin and with most of the new things in the game it seems SE has gotten it right and Def a.k.a. Vit tanks are back this head gear = owns everything else so far
