"It's unfair: 206 lbs HWs have to compete against 265 lbs HWs!" People who weigh 206 lbs don't fight at HW. They don't even fight at LHW. They fight at MW. Fighters like Anthony Johnson who weigh 230 lbs have no problem cutting 25 lbs to fight at 205. There are 125ers like Ian Mccall who cut just as much. People who happen to weigh 235 lbs can easily lose 5 lbs by skipping a meal and taking a piss before cutting to LHW. That's why only those who weigh 240+ lbs actually fight at HW. "Okay but 240ers have to compete against people who cut to 265 lbs!" A 240 lbs person has no right to complain about his opponent being too big. 240 lbs is the optimal weigh for a HW. The best HWs in the world like Miocic, Werdum, JDS and Cain all weigh 240 lbs. The best HW boxers are 230-250 lbs. Even the best HW wrestler (Taha Akgül) is estimated to be in the 240's. Once you reach a certain weight, size is no longer an advantage. A 150er might stand no chance against a 250er but a 250er can handle a 350er just fine.
