It is true that this effect is roughly the same as in A2... but this is A3, so we cross our toes and hope for better.
Dumping the collective in a real chopper will have quite a violent effect.
Not asking for vortex ring state simulation (although that would be so nice), but a more realistic impact from dumping the collective would make flying so much better.
Doing crazy acrobatic slides to lose altitude is quite detrimental to the whole 'realism' thing :)
