You are missing the point. Many doesn't mean everybody; moreover, try to imagine real many in your country. Besides, you are speaking of students under most favourable conditions, and in these you can never tell whose success is to your credit. Extensive exposure to L2 does influence the process of learning and motivation, but can't speak in favour of a teacher's skills.

In your circumstances using L2 only is inevitable, but is it really advantageous. I know a lot of students who have learnt English with native speakers and their knowledge of English is rather poor - but self-assurance, the latter being not an advantage at all, since it hinders further progress.

Exactly! That's where experience speaks out. It's a teacher's duty to keep students under control and to time and measure whatever is being done in class. It really is like a drug for freshers (a headache as well) but is overcome with time and experience by those who stay in business.
