Even though I am a proponent of the modern era and turn in disgust when I hear romantic buildup of a fantasy past... I completely agree we should have same day weigh ins. I don't really care about the number of divisions but I think the WBO belt should be amalgamated with one of the other major bodies and go back to having just 3 belts again and with only 1 champion per belt and division (none of this regular and super champ shit).
And also there should be mandatory unification after certain criteria to avoid keeping the belt separate for reasons of money.
Some things were better in the past. Particularly the weigh ins. They leave fighters dangerously dehydrated and the weights can be grossly disproportionate to actual fight weight. I like 12 rounds better though. I feel it lends to more explosive fights and 15 rounds leads to more featherfists and pacing.
