Any fighter over first level is likely to have a better AC and hp than you have given your sword (which, as has been pointed out, is actually only a guideline, and is up to the DM). So the goblins will kill the sword faster than they will kill the fighter. Chances are they could do it in one round in fact if they all attacked it. And you have already established that people in the world are too stupid to carry spare weapons. So the fighter with no sword is neutralised - the goblins can finish him off at their leisure.Rubbish!
If six goblins started just attacking my Fighters Greatsword (AC 19, 18 HP) instead of the Fighter (while he cuts them down mercilessly) how is that the best way for those goblins to neutralise him?
If it's an effective tactic it would be unrealistic for the goblins not to use it.How is that in any way realistic for those Goblins to do?
If it's not an effective tactic for the goblins, then it's not an effective tactic for the monk. You can't have it both ways. It's ether effective, and everyone does it, or ineffective, and no one does it.
