Nah, Aana's suggestion was really spot on. Brd/Mch used to have lower weapon damage (I'm guessing at some point they changed this because now they are all the same) and it wasn't ever an issue because it was just their baseline. We know that 1 WD is equivalent to a certain amount of str, so they should still be to balance DPS to be roughly the same while giving tanks a meaningful upgrade path on the right side accessories. Just adjust where the damage comes from slightly, it doesn't have to be weaker or stronger - just a shift.
(personally doesn't affect me as I'm not dropping the gil for crafted accessories, and since my co-tank already took that dive I'll get the raid drops anyways lol)
