@cc- Yes the American brothers giving talks in foreign languages are notoriously poor speakers of the foreign language. In my experience- that goes all the way up the food chain. I remember hearing Wally Liverance- a Gilead Instructor- speak in spanish. It was like listening to fingernails on a chalkboard!!
But you cant diminish the fact that the assemblies are more and more just canned, proofread manuscripts without an ounce of reality or actual human emotion. Now- 6 years out- I cant imagine going and listening to a seminar for a full day and walking away not being able to remember a single interesting item.
