The theory advanced seems to be, from the perspective of a given DM
1. play will be unsuccessful unless they run it in the way they are good at
2. players don't impinge on play success as they can be swapped out for those that fit
and from the perspective of a given player
3. play will be unsuccessful unless DM runs it in the way they (the player) works well with
4. but DM doesn't impinge on play success as they can be swapped out for one that fits
I feel like this theory rests on over-simplifications - play is successful or unsuccessful, and DM and players simply are the way they are. There's no room for increasing success with a new approach or growing skill. I'm not saying this is what
@Emerikol intends to argue, only that the words I quoted seem to contain those implications.
