I would love for the WBC to someday become a mid-season summer 20+ day event and more independent from MLB rules / limitations.
At this point MLB / MLBPA are holding back the WBC from its full potential by treating it as exhibition spring-training event. Limiting pitching counts, capping outings, pulling players from roster sucks and takes prestige away from the tournament
I think baseball has an opportunity to grow into a true global sport.
With that said. I get that MLB, NPB and other leagues are first and foremost a business. They will do what is best for their business
