Teams get awarded with time when they cap the point - not before. It's a fight of the CP between 2 teams. If you can't cap this point, you deserve no bonus. The pit isn't that deadly. You can escape the spam (should there be any) or incoming pyro. Also this is a team fortress, not solo fortress. Not everyone should stand on the point. Some of the team should keep an eye for the exits where enemies come from. If everyone stands on the point capping it while enemies approach, you are doomed anyway. That point really isn't hard to take. Seriously.
