Is this a hack or BRD OP issue?

WM and GB both remove the damage penalty. When it is in effect tho, like in lv50 frontlines, dmg is actually reduced as much at close(melee) range as it is from being very far away. Melee also have a slight natural resistance to physical damage

This is half-wrong, WM/GB remove the 1-14y penalty, but brd/mch get a penalty if they are 16y+ no matter what.
