Fixing stalemates alone will do absolutely nothing to fix sandbagging. There are a few (10-20 heavyweight teams) that have a very hard time matching or are so skilled that they will always stalemate each other. Aside from these 10-20 teams, the remaining 95% of teams that use this tactic will continue to do so, because it gives such easy matchups against non sandbagging teams. I agree with Jakob's statement that atomic defenses will help end stalemates....but only for heavyweight teams, the problem is 95% of sandbagging teams will rarely if ever meet full atomic defenses in large quantity because they've artificially lowered their weight so much, and may sandbag even moreso to prevent these matches.
Im all for the two defenses per base solution (originally Gail's idea), because I feel it will address both problems in a very positive way.
Unfortunately, for some reason, BHG has chosen to not care about this issue. And, they are the only ones who can help.
