Why can’t every Smackdown be like the Mix Match challenge…

The Goldust/Rose team today was hilariously brilliant against Mr and Mrs Uso. Goldust can still go like crazy and was seemingly having an absolute blast out there. Why can't we have this kinda great stuff on the main
shows? Last week's Bliss/Strowman combination was inspired, matches go for ~20mins and tell a unique in-ring story. Whats not to love here? Surely this is a proof of concept that letting these talented guys and girls go out there and do their own thing works
more often than not…

​Yeah, but just think how much BETTER it would be with all 30 writers coming up with great material for them to memorize!  
Also, according to the Observer, WWE isn't really happy with the viewership patterns thus far, so it might be a one-time thing anyway.​
