You don't actually need to try and hard counter the enemy team alone, you know. Anything to break up their formation will help your team.
Dropping a Comet in the midst of the enemy team would force them to scatter and desync burst. Firing a MCH LB at the RPR might force them to instinctively Guard, which desyncs them from the rest of the burst. Diving in on a tank and then splitting off from your group would very likely split off half their team to chase you down, reducing their firepower.
Basically anything you can do to delay the enemy burst helps your team out, the only problem then would be on whether or not your team has the awareness to not die, which is something no one but themselves can help with.
