DWT was very basic and minimal... that + her perpetual lateness turns people off from going to her shows. DWT was fun because the crown turned up to her music, not because of amazing effects/choreo/vocals/etc. it's hard not to have fun when you're bopping to songs the entire crowd can sing along to.
she also needs to milk europe for all it's worth and visit every urban hub in the US. i know she could sell-out more shows here but she's lazy
