Raw intermediates (the vast majority of us) need to actually practise the lifts. Rotating them so you only deadlift and free squat once a blue moon doesn't allow that. The equipment required (bands, chains, different types of bars that allow you to rotate the ME work, GHR and reverse hypers for RE work) simply aren't available to the vast majority of trainees who train at commercial establishments and or at home.
Finally the presence of westside lifters in any raw fed are enormously under represented. Everyone knows that.
Also don't give me that shit that 'people who don't train with louie don't train westside' or 'westside is constantly evolving' - its standard texts are whats released by elitefts and the westside site and always has been.
