The right hook is currently the worst punch in all of cRPG. I'm not sure if it can even register a hit that deals damage. However, if I was going to punch someone in real life, the right hook would be my go to power punch. Sure, its a little lacking on range, but its all about power.
Also, nerf backhand or change it to a left jab. You should never throw a backhand in an actual fight, it should only be reserved for disciplining the ladies who get out of line, yet it is somehow arguably the best punch right now.
