Most of all, the players need to be likeable and have some character for the viewers. I'm all for a newbies season.
I've already marked the "Beauty" team off my list. The "Brains" might be good to watch unless their IQs dominate their common sense and social adaptabilities. Before the merge, the "Brawn" might be the team to root for unless they flex and high-five 24/7. After the merge, it's anyone's guess this early out.
It all depends upon upon requirements for the categories. Will the Brawns be dumb as rocks and ugly as scorpions??
Everybody has a mix of some Brawn Brains and Beauty.
Even the weak, the dumb, and the ugly.
For someone like Monica or Laura or anyone else this season there would be a big question as to which category to place them in.
And then there is that intangible people skills, the social game, and uncontrollable luck, and those people who would drag you to the end because they think you are a loser and they can beat you.
And by the time they mix the tribes by the 4th week it will all be irrelevant.
