There's something to be said for keeping the top titles special and doing the hot shot angles with the secondary titles. We hardly ever saw Hogan defend the title on TV, and when he did it made it seem like a big deal no matter what loaf he was put in there with. I feel the same way with Brock, yeah him being gone for months isn't great but when he is around you know shit's going down. They're even doing it with Jinder too. No matter how you feel about his push, it's going to be a big deal when he gets beat.
Hotshotting all the titles is what made them all worthless in the 90s (hi Vinny Ru!), but doing it with one while keeping the others stable is okay in my book.
