I'm just spitballing- but in essence, I think there'd be a state or two that would get sued if they just straight out eliminated points altogether. The basis for the lawsuit would probably hinge on everyone being refunded at value for any points that were washed away. So if there were to be shifts to random draws, I think states would be well served to avoid the potential of a lawsuit or refunding folks, and my initial idea is to force folks to combine their points for one species.
Basically if I have 10 points for Sheep, 10 for Moose, 10 for goat and 3 for elk, I would be required to combine them all for one species, i.e. 33 pts for moose. The points you gave up, sheep, goat, elk, would clear the way for other hunters that maybe chose that species instead, and then you'd start applying in the random draw pool for those species while you apply in the bonus pool with your 33 points for moose until those points are used, at which point, you also enter the random draw if the state isn't OIL.
It seems like this would be one way to phase points out altogether while avoiding (some) of the backlash from those that have spent their time and money building points waking up to all random draws some day.
Obviously, I think some species would get very clogged with stupid point totals- Sheep would probably require 100+ points. But maybe those top-tier deer and elk hunts could then be had after a couple years at a much lower total that the 20+ points we see now if that's what you chose to combine your points toward. Younger hunters/those with less points would do well to apply for Elk/Deer/Antelope, while those with the most points/age would probably go after their dream hunts of Moose/Sheep/Goat etc. This would provide some semblance of equity, in that the younger hunters would still get a quality hunt, while having many more years to try and draw a random tag. The old guard would have a simplified drawing with less applicants to compete against while they look to use their points before they die or are physically unable to enjoy that hunt.
For my purposes,
@RobertD, I think the state's would be best served to not separate Deer/Elk from Moose/Sheep/Goat etc., as it would clear points out that much quicker. If two or three states switched to this method at once, think Montana, Utah and Arizona, hunters could combine their points in a more diversified front- say Desert Sheep in Arizona, Elk in Utah, and Bighorn Sheep in Montana.
Just a thought.
