I say this with love, but I have a few issues with the BTW Ball:
-Born This Way and Judas are cut short at the end, which are THE BEST PART of each song. Usually her vocal harmonies slay at the end of these songs, but she just walks off stage

(and Judas's second verse is skipped over too)
-Marry The Night is cut short. I understand that it's a long show, but it's the finale and one of the best songs of her career--it deserves to be sung in full. Most nights she doesn't even sing the "COME ON AND RUN, TURN THE CAR ON AND RUN" part and is instead trying to put on her keytar

-Electric Chapel sounds awful live. It just does...and I don't understand...and is she actually playing guitar? She makes her voice sound really gritty on purpose and it sounds so different from the studio version.
-Paparazzi. Why the hell does Mother GOAT "sing" the first half of the song for her?! It's one of her best tracks and it gets paid dust.
I know she's trying to fit in as many songs as possible, but it sucks that she has to shorten most of the songs. Most of the shortenings I'm okay with--most of her singles from TF and TFM have been played to death and were "showcased" at past Balls, but at the BTW Ball, standout tracks from Born This Way like Judas and Marry The Night deserve a full performance.
That being said, everything else about the show absolutely slays. It's impressive how long her show and how she still manages to sing the **** out of The Edge of Glory acoustic every night. I've watched videos from most of the dates from this tour and the standout performances for me are: Scheiße, Bloody Mary, Americano, The Edge of Glory, Fashion of His Love, Black Jesus, and Princess Die.
