Or just add STR back into the damage code at 0.5x on top of DV.
Going with the troll example: A troll that can put their fist through your skull and touch the wall behind you should be just as able to pin your skull to said wall with a knife, or a pen, or a fragging spoon.
This argument has been going on since the QSR came out, and it's just going in circles. The rub is in 6th edition, high STR characters have been pigeonholed into unarmed combat to be able to use their strength. This is restrictive to builds, and not very much fun. The flip side is that with the reduced damage values, allowing full STR back into the damage values makes high-STR characters potentially 19 DV melee gods.
So go down the middle at STRx0.5 and let players strength matter.
