I think it depends on point of view... do we really want most of the talent rows to be just some utility that we don't really care about and has no meaning whatsoever for our actual gameplay? It was a complaint about MoP talents and reason why many screamed bloody murder at these and the whole way MoP talent system change worked out.
I think current way where talent rows offer very meaningful changes to your rotation or gameplay in most of the rows is a better alternative. The issue is the same issue that isn't solved for many years now - talent balance and quite honestly I have no illusions about this being solved anytime soon if ever, it's just how it is really - when shit's so different, then there is always mathematically best option after all. For Aff (ST at least) it's pretty much all rows all actives (cancer, IMO) and for Destruction it's the opposite.
