I was in that same match with you. Even without the bots, I feel like much of the time players simply don't care enough to try. The rewards for simply being present for the short match make it too easy for folks to Leeroy Jenkins about the battlefield without regard to the objective. It's pure luck if you end up on a team that cares about trying their best. I haven't been able to think of a good solution to the problem yet. But yes, that whole bot thing is frustrating too. At least the underachievers have the potential to benefit the team, whereas the bots completely handicap the team.
