Sometimes I think there should be a height restriction tbh . although I can also see the problems that introducing something like this could create Most people don ' t see it this way , but I don ' t like seeing 6 ' guys fighting in lightweight . Not only are you exploiting the shit out of the system by fighting shorter guys , but you ' re starving yourself , which just isn ' t healthy at all . You could argue that it doesn ' t matter because they both weigh the same , but realistically these taller fighters rehydrate quite a lot and on fight night usually outweigh their opponents significantly . If there were a reasonable limit , there would be less health risks with these people . Maybe in leiu of a height restriction , we can get an actual rehydration limit , so that people fight at a weight close to what they actually weigh , rather than dehydrating 20 lb to fight smaller guys . Better for fair competition , and for everyone ' s health .
