You might consider taking a look to verify if the minor force from the Medusa set is being applied to the dummy. When using Medusa on a MagBlade, the minor force does not get reported in Combat Metrics (it DOES get reported when parsing on the live servers) and parses seem significantly lower when compared to others. When I throw Barbed Trap on the build the Minor Force does show as being applied, just not when using only Medusa.
