Tail rotor issues and the FFS
Just before you get carried away just remember that unless your simulator has been programmed with actual flight data then it would have been programmed using a mathematical model and given the evidence I have seen thus far I would be a touch sceptical.
The major instinct you want the trainee to grasp is an instantaneous (or as near as) recognition of a TR malfunction and if it is one that involves total loss of directional control to then lower the collective fully whatever the phase of flight.
A few seconds later then you may have a chance to reassess the collective position according to your circumstances but I believe we can say with some confidence that the longer you delay your reaction the more problematic the outcome.
