What’s with all the people using super aggressive tactics in the Cosmodrome GM?

I’ve gone through about 5 fireteam finder teams and at least one person in each group has a super aggressive build that leads them to pushing way far up and dying in terrible spots.

Maybe I’m just old school but I’d much rather sit back and take out enemies from a distance and take an extra five minutes per run to guarantee a clear and loot rather than waste 20-30 minutes on a run that fails in the hopes of saving that extra five minutes because you wanted to face tank unstoppable champions and Hive Lightbearers.

I’m not ripping people who actually can survive using these tactics either. 2 out of my 5 runs had people who generally stayed alive.

Edit: I’m mainly talking about the final boss room. I know you need to push the payload to stop infinite spawning enemies.
