I don't recall anyone in the Freezone who needed much in the way of OT
Depends what you mean by "needed."
"Hey, would you rather do an intensive of boring crap or start on the super-duper hot stuff?" contains an offer not likely to be refused. The problem is when the set-ups actually *are* needed because the person isn't in particularly good shape, and their perception isn't up to running the stuff on OT2 and OT3 because their internal world is too "noisy."
