With the buffing of damage boost it would be pretty great to give damage boost to WF. It would give them a purpose when rolling melees again, Horc would still be on top for Barbarians and classes with damage boost, and Warforged would be on top for Fighters and Rangers.
It makes sense for WF to do more damage in melee than Humans and Half Elves, and it would give Warforges more use than just for Sorcs and archmages.
