3 reasons why various WWE Superstars have appeared on both RAW and SmackDown LIVE recently

#2 To induce Interbrand rivalries

Brock Lesnar had an Interbrand feud against Randy Orton in the summer of 2016

The biggest problem associated with the brand split is that one brand may become stale after a few months from the latest Superstar Shake-up.

While SmackDown LIVE did a brilliant job at mixing things up last year, RAW had a terrible time with its roster. The red brand had to recycle most of its feuds throughout the cycle of 2018. Repetitive feuds, stale storylines, and filler segments were prevalent throughout the year.

Thus, having some Interbrand rivalries will help to spice things up for both the red and the blue brand. Since WWE is only having dual branded PPVs, it would be a good place to ignite some rivalries.

For example, on the next WWE PPV - ie, Money in the Bank 2019 - WWE could spark an Interbrand rivalry during the ladder match, where both RAW and SD LIVE Superstars compete against each other.
