Lol, this idea was "wouldn't have been cool if", implemented properly it would have been no different than STR vs AC instead it would have read STR vs STR.
Big deal. Not complicated. Maybe, even simpler than its current form because defenses are written into the stats themselves rather derived from one of two stats.
STR 18 +4/14
and at 10th level:
STR 18 +9/19
The complication.
Since the game is not implemented in this way it is a non-option, without a re-write of PHB.
I took it as a postulation on something for a 5e, but which might take too much choice out of the defenders hands.. but which had some merits even so...
