Nonsense. NPAs are easier than ever, even if you don't have VNAV. Track diamonds, Track Selectors instead of only Heading Select, FPA (can be precisely set to eg 3.28°), Vertical Speed that can be set to the 10ft/min, Autothrottles, big navigation displays showing you and the PM where you are for orientation...
Not to mention, in some countries, Distance/Altitude scales on the charts which remove all of the profile guesswork...
