I use Lieutenant's Sash myself. I'm not entirely sure I'd drop a consistent damage reduction like that for something that's actually going to increase the damage I'm taking 1/8 of the time. It's only -2%, but always remember that capping in any other slot allows you start gearing MDB in slots that would otherwise be occupied (Mujin Stud instead of Merman's Earring, etc) Granted, I could always make two seperate MDT macros, but a lot of times there's little going through my mind when throwing on a DT set other than "oh shi-".People rarely use the waist slot for MDB/MDT (MDB+4 for PLD? Slipor Sash for mages?) and can cap out easily with other slots and Shellra V
But yes, please, please do this SE.
