I believe you are right and that the tried and failed point banking should not be brought back. From what I understand point leap is what the CPW is planning on to get rid of all the points they have issued.
Something to think about is that point banking will take what it takes to draw +1 so lets say you have 11 points and decide a mid tier elk unit first rifle hunt that is now at 6 to draw but will go up to 8 with point banking +1 so you will burn 9 points for what is now a 6 point unit.. That will leave you with 2 and not able to draw anything.. So the 11 point guys will figure this out and go after the archery tags in said unit as it is only 3 points to draw but with banking it will jump to 5+1 and leave you with a archery unit that could have been drawn with 3 this year easily taking 6 for someone who is "banking" points..
If you dont have points and as stated there are a ton of hunters who hunt and dont just gather points. These guys will still want to hunt and know how to get leftovers ect so leftovers will become a thing of the past.
IMO point banking will unless you have saved points point banking will essentially cut you out of any chance at a license for any unit that currently takes any points to draw for the next 5 year cycle. I also believe the people who believe under point banking any unit that currently takes 1-4 points to draw will leap to take 2-3 more points the next year to draw.
