I'd pay for that shit. But it seems like they pick the cast to balance out strong and weak and bring drama at the same time. Like they tell themselves OK we can only have 3 alpha male vets per season and 3 alpha rookies. Like they wont put Jordan and CT on same season (or maybe they have). Honestly hard for me to remember all seasonals and everyone who was in each. If you check out the challenge subreddit there are some hardcore fans that remember everything (or google it and act like they do).
Back in the day it was stacked with beasts: Evan, Kenny, Brad, Darrell, CT, Bananas, Wes, Alton, Derek, Landon, Mark. Most of them were on same seasons together. But the challenges were different back then for some of those guys...it only got more intense once these dudes got older. I'm sure it was hard to get them out of their normal lives to come back. Because back then they weren't paid as much, have social media $, or have the large prize money like there is nowadays. So there is more incentive for cast to keep coming back now.
