#3. Superstars freely appearing between brands
As mentioned, the original idea was for three superstars to appear on the opposing brand. Instead, we got five on the first night. Elias was the fourth and Lars Sullivan, the fifth. But this isn't the only case recently of superstars freely appearing between brands.
Michael Cole explained the extra appearances as the Wildcard Rule "still being in effect", the same way superstars traded brands even after the shake-up. In that case, Cole mentioned that the Superstar Shake-Up was "still in effect".
Fans drowned out a popular wrestler with 'She's a racist' chants recently
What's clear is that WWE is going to give far less emphasis on superstars going between brands and this has been the case for a while. John Cena was originally the only superstar labelled as a "Free agent", where he had the privilege of appearing on both brands. It added novelty to it and no one opposed, it, because it was John Cena.
Hopefully we're wrong and WWE goes back to brand exclusivity soon.
