I say the haste only helps those who already can wear lots of Haste gear...in this case is MNK. So a MNK/DRG would have 16% Haste at lv.40, fully geared...pretty nice stuff.
As i understand it, the Latent Effect applies to our Sub-job. So your subjob should be as such to benefit from the type of Latent Effect. One such example i was just reading is the Wyvern Earring with +5% Haste. The sub would have to be DRG since they are the only job with a wyvern, but most people feel a DRG sub is a waste, thereby implying the earring itself is a waste.
If I'm wrong and someone reads this, please respond with a quick corretion. Thanks.
your correct..but! certain jobs do benefit from such akward subjobs. Players really should experiment more with there gear and subjob combinations before they bash an item/ job.
MNK WAR THF DRK RDM SAM NIN, benefit from /DRG at certain levels, with the correct gear set up it works beutifully.
