I dont think it has much to do with whether it suits one or not, or whether they wont like it or not.
I think it is about changing something that didnt need changing.
Keep the Tour of Sufferlandria, as it has been for the past decade.
Add/include a new challenge, call it Tour of SYSTM which is a tour of what the whole platform encompasses. Let those decide whether they like it or not, and/or whether it suits them or not.
There is no need to go changing something that is already exisiting, to be replaced by something that can become its own entity.
The act of raping the longevity of a succesful and long standing challenge to fo into something else is what is not liked, and or not suited to others.
Make the change by creating something new.
Keep your principle in place as the skeleton, and lets change/tweak every workout to something it is not today as the meat on top of the skeleton. You will like the fact that the workouts are not the same? The principle remains but the body has changed.
One cannot have shades of grey to suit our own preferences. I am only okay if thet change X and Y, but not X&Y plus 15 others.
Change can be good, if the change is good.
As an example, how many long serving SUF members requested that original SUF workouts be contained in their original format, instead of the revised format to lessen whatever. Fight Club has its remastered sibling in the library, Tour of Sufferlndria can have its sibling of Tour of SYSTM, the change being something new is added whereas there was no 2nd Tour. That’s a good change.
Are you of the opinion that the Tour of Sufferlandria needed to be changed? And hence, you have no issue with it being anything else but the ethos of the original ToS?
