Nice idea, but way OTT in its present form.
Needs to be 'de-tuned' significantly to be more realistic, but with that done, I feel that it would be a significant improvement, and make scoring much more realistic.
However, it WILL put off new/bad players, so how about adding it gently, with no effect at hack, then increasing the effect by about 15% for each tier, so only the top players feel its full impact, rather like higher tiers having to use longer tees?
