I would have laughed at your question just a couple of months ago. But I am facing the same issue in my league. Fortunately, I am still leading but there is this unbeaten team that uses the same bloody tactic (see thread related to the 3DC-1-2-3WAM-1) no matter what the opposition comes with. This is p... me off big time. I cannot accept a tactic with so obvious weaknesses to remain unbeaten for so long.
