Way too big

-it doesnt fit in most of the venues
-if she has to keep running from side to side shes going to be out of breath.
-if they decide to use the main stage only. Because the venue is too small, they have to make new choreos cause the dancers have less space
EDIT:
- Breaking down and setting up this stage every night will take a lot of time and people, people means more money. Record labels dont like spending money.
- transvering the pieces of the stage will require a lot of trucks and planes.
