Nope, x4 brave DD = 13% + one improved = 11% so thats 13x3 39 + 11 = 50 max DD.

There is a cap on glacials weapon and armors though. Limit is 40% hp/melee/magic/ranged. So either they turn back the shiny option stones, either glacials won't be ever used, either they turn back the old glacial stats cap.
