Should we have a 5% rule on ring weights?

The modern techniques of cutting weight for the weigh in then pilling in back on with protein shakes for fight time, is making a mockery of the weight division that are in boxing. Fighter can come in on fight night 2 or even 3 weights classes above the division they are fighting in, and outweighing their opponents by a stone or even more in some cases. Do we want boxing to becoming less about skills and more to do with who is best at cutting weight? I propose that a fighter can only rehydrate 5% above the division that he is in or only to the next weight class. Cutting so much weight can also be detrimental to the fighter himself and can also water log his body by taking on too much fluids. This ruling would make boxing better, have boxers on a level playing field where skills, heart, power and speed are the important factors rather than size. I've been impressed by some organisation that also hold weigh in at 30 days and 7 days before the fight that boxers have to meet so they don't have to kill themselves for the weigh in and they will be fitter and stronger for the fight.
