I think the dex on them is designed to help with the relic WS, which is said to have dex as a mod. Although there might now be better pieces to equip for WS, the pants weren't designed to be useless.
i just got these today,no one else wanted them and i had the highest BST in the alliance...woot i guess....i would only wear them just to have the full monster set,cause otherwise....they suck...
ya this item is dissapointing but its great for a switch gear macro. Just throw the pants in switch gear along w/ your dark staff. Now when u rest u get faster mp and hp recovery, then put your preferred bst pants on in a switch gear macro for either ur charming or fighting gear and ur all set!
Seems rather subpar compared to the normal AF trousers that come with +4 charm. The Dex is nice, but there are much better pants at that level you can switch to for attacking (Thick Trousters/Ogre Trousers immediately spring to mind)
