Oh he isn't interested in defending belts but he wants title shots? That's BS. If he wants a belt then he can defend it. If he is interested in winning the LW belt then he must be interested in defending it. If he is interested in defending a belt then he can very well fight for the WW belt and defend it.
IMO no fighter should be allowed the chance for a belt if they have no desire to defend it. Defending is what legitimizes the belt. It's disrespectful to the sport and the division to just purposely vacate because you don't want the burden. Then don't fight for it at all.
It's your opinion.
