I find it strange that out all Omen gear/accessories, Blue Mage is stuck on only mage accessories and the mage body from Kei. The only melee accessory that BLU is on is "Ilabrat Ring" and that's about it. Apart from the Omen mage body, BLU won't gain any special benefit from some pieces. the "Enfeebling effect duration" doesn't affect blu spells, neither does the "Absorb Effect duration"
And I won't forget how when reisen gear was released, the merlinic set came to mind when they responded that it was purely for back line jobs and not intended for blue mages. Now it appears to almost be the opposite with Omen gear/accessories
