The ASA legs are great for a Mage-Melee build i got the Haste+3% acc+7 ones for my AWESOME SMN MELEE BUILD.

The ACP body is actually good for 1 thing, Quick Draw Recast -5 for THF/RNG W00. Also i'm pretty sure for BST its the only body that offers Pet: Double attack and w/e.

They still fill very niche roles, but mainly just for Pet jobs, or jobs who like to melee but dont get melee gear :3
