These gauntlets are quite pathetic for Rogues.
For ToV you need many 55+ groups and lots of time to aquire these gauntlets...
Crystal Chitin Gauntlets (20Ac 10Str 35mana) are better than these and drop in Velketor's Labyrinth. A Rogue only needs a hunting parter or two (highlevel Rogues with uber gear can even solo there) to aquire these.
Sure, they are rare, but it takes *way* less manhours of camping to get CC gaunts than Shadow gaunts!
