With the new update, this isn't worth it for NIN or SAM. Shura Togi is going for around 1.2 mil on my server. Think about it...
Haubergeon: The positives
STR+5 = 5 Attk
DEX+5 = 5 Accuracy
Accuracy +10
Attack +10
Outcome = 15 Attack, 15 Accuracy
=======================
Comparing Hauby to Shura is quite simple. Only thing we are missing from Shura is an extra 5 attack... wanna spend 1 mil for 5 extra attack? Go right ahead. The negatives for comparing the two isn't much really either. For Hauby we are losing -22.5 Evasion, it may seem big, but Ninja shouldn't be tanking in this armor anyway, and on SAM they aren't a main tank at all unless you are a SAM/NIN tank type, but that's not in our equation at the moment. And the negative on Shura is -50 HP.
However, for MNK this is a but different, but their AF2 gear is quite nice as well. I myself am a 75 SAM and 75 NIN, and Koga Chainmail comes close to Shura Togi if not better incase you decide to go NIN/RNG (I also like the colors of Koga better as well). Now depending if you're having trouble getting Koga, why pay for something when you can have it for free?
My conclusion is, with the update, there are different solutions before getting this armor piece. Just really all depends, I'm not going to get into the technical field of people arguing about WS damage, this is only the true science of it.
