#3 Universal Championship
Brock Lesnar, whether you like him or not, is the most celebrated athlete in sports entertainment. The problem arises during his stints away from the company, to be honest. Unfortunately, like we've seen in the lead up to TLC, Lesnar's time away really affects the product. With the top title not on the show, the quality does suffer immensely.
I had genuinely thought that Reigns was a good Champion. WWE seems to be reluctant to put the title on Strowman, for whatever reason. Maybe they want his coronation to take place on a much bigger stage than Crown Jewel.
Whatever the case may be, the quality of the show suffers owing to the fact that The Universal Championship doesn't make a weekly appearance. But then again, this probably puts heat on Lesnar so that the eventual winner can benefit much more.
But yes, I think Lesnar should drop the title for the betterment of the product.
