I once played a course that had a certain hole on it that the fairway was so narrow, that I speculated that if you took the 10 best players in the world (Will, McBeth, Feldy, etc.) and then also took 10 middle of the pack Advanced players, and everybody got to throw 5 drives, you would probably see there was very little difference in how successful each player did, so much so, that the middle of the pack Adv guys would do about the same as the top 10 Pros.
And assuming this all played out, it is pretty clear that the hole had removed skill to a large degree and rendered it more about luck.
Now move to the 2M rule: take a hole that is so heavily wooded, and the only route is through dense trees/bushes, so much so that every player stands a very high possibility of hitting some vegetation. In this case, the 2M rule has had the same effect, mitigating skill and replacing it with luck. This is an extreme example, but holds true in some cases. The interesting thing about this thread, and so many others on DGCR, is we have people of varying experience and skills, speaking in such absolutes. If the heavily wooded hole with only one route was common on your course, that would justify getting rid of the 2M rule, especially if you hosted tournaments with people playing for money, prizes, etc.
Also consider the varying impacts on a players score - the top Pro who is fighting to roll up a 1060 round and likely only win by 1 shot, versus the 920 player who will be rolling up a couple double bogeys and several single bogeys.
And going back to the start of this post where I talked about the extremely narrow fairway - guess what ? A little time passed and bunch of big name Pros came to town and played that hole, and 2 guys immediately commented that at least one tree had to be removed from that fairway - Climo and Feldy !!!
