Let's face it, men are stronger, faster, have more endurance and are way better at survival aspects (building and maintaining a fire, obtaining food and water, etc). The challenges, even the supposedly gender-neutral ones are still going to be a blood bath. Not to mention the fact that women are insane in a group.
Like in Nicaragua Young vs. Old, we all know they will shake things up soon and rearrange the tribes, but by then so many of the women's tribe will have been voted off that they'll be a minority outkast where ever they end up. The first several evictions will all be women, the ones that survive will get pagonged.
They got a raw deal.
