No deal.Lol @ you trying to sound like a know-it-all just by repeating yourself and saying what is already known.
Everyone knows how the qualification rules work and I simply disagreed with part of it. You can't compare a fed cup team of four with an actual delegation that plays a team sport at the Olympics. Even though fed cup is a team competition, tennis remains an individual sport with an individual goal at the Olympics (which is Maria's case) unless you're playing doubles or mixed. At the end the rules are the rules and that's it, some are fine with it, some are not, some don't care. Deal.
Your disagreement in reality is the proof you do not understand the basics of the Fed Cup and any team event.
1. Fed Cup is a team event, all players are simply members of the team. They are with equal rights before the play begins.
2. The most basic right of any sportsmen is the right to participate in a competition, but the player CANNOT be forced to play. A player even cannot be forced to show on the court, he/she could lose the match being far away from it.
3. The final decision to compete or not always belongs to the player and he/she could take it at any moment. Even if the coach or the captain of the team decides the player will play, the player could agree or disagree.
4. In each team event of any sport there is a minimum number of players who could win the competition. For Fed Cup that number is 2. For football (soccer) it is 8 and so on. The rest of the members of the team are not obligated to play.
That's why the Fed Cup rule you want changed will never be changed. It simply represents the basic rights of the sportsmen and the team.
