I have seen a lot of people missing the point on the IV ban. There is a significant contingent that seems to think that the purpose of the IV ban has something to do with weight cutting. This is wrong. It is not about weight, but to prevent blood doping and masking PEDs, per USADA protocols: http://www.usada.org/is-it-prohibit...g-iv-infusions-for-re-hydration-and-recovery/ Here is the most important quote: The other thing to take away is that oral hydration, done properly, is just as effective as using an IV. The only people who are trained on fight night will be the people who fuck up their cut and rehydration, same as now. TLDR: There is not going to be some great revolution in the weight classes. Weight cutting is here to stay.
