I see it once in a while beeing an instructor in the sim, crews start the descent late, are using an idle descent mode (level change, as the thai guys did) to chase the path, and do not have any gate to stop the massive rate of descent. Furthermore they are not using the vertical profile displays to avoid coming low. Just a nice example of THREE pilots who lost their situational awareness completely.....
Non prec approaches are nowadays as easy as ILSes! It just needs a little bit of preparation and maximum use of the modern instrumentation we have nowadays...
