This part of your post I fully agree with.
TR failures / control restrictions are VERY serious in helicopters UNLESS one is VERY familiar with the mechanics.
It is probably the LEAST discussed/rehearsed/trained evolution in the rotary world. AND the most damaging if handled badly
The other thing I see wrong is too many folks fail to understand just how much "Yaw Control" they do have even when the "normal" control system is not working as it should for any number of reasons.
