AMDEC - that is the same Bell myth used to disguise a poor design and unfortunately reproduced by the FAA.
If you put a TR on a helicopter that can't cope with certain wind conditions then you either impose handling/wind limits on it or put a bigger TR on it.
Bell sales would have been affected by a wind limit that competitors did not have so they invented LTE as an explanation.
If your TR can't produce enough thrust to maintain or correct a heading then you have a loss of TR effectiveness. That is not the same as not putting enough pedal in.
Plenty of people have been spun round by weathercocking in helicopters but it is often lack of anticipation rather than poor TR thrust.
Losing ETL on the MR also affects the TR and you can suddenly experience an increase in Power required from both rotors - you raise the lever to compensate and also require more power pedal - both to compensate for the loss of ETL on the TR and to counter the increased torque reaction caused by you pulling more collective.
