I’d say, not that Novus Ordo invites abuse but that the the modern esthetics (I use the word loosely) is the abuse. One can tighten the rubrics, ban the Orans and hand-holding in the pews, ban sneakers, ban beach attire, give everyone voice lessons and electric-shock the faithful into singing, and the external signs will improve. But still, so long as the congregation comes to celebrate themselves such as they are, as modernity teaches them to do, the Sacrifice of the Mass is obscured.
If I were to change one thing in the Novus Ordo, I would turn the priest eastward.
I believe facing eastward is the normative position in the OF, and facing the congregation is an indult. But, in practical terms, that has been superseded.

Something which isn't mandated in the "Novus Ordo" in the first place. (And yes, it should be changed ... or rather that the change of the priest's orientation should be reversed.)
