Yeah, it's going to be fun. Hope we don't see Dar banned from PROGRESS though - I think the most likely outcome is either Will losing his title shot, or the Riots winning the tag titles.
You can say that about any flippy move, not only 'excessive' ones. An elbow drop is far easier to hit perfectly with any regularity than a moonsault, but that doesn't mean we should do away with moonsaults.
TBH, I didn't even notice Sydal didn't hit Acid flush until you pointed it out, probably because Trent sold it well.
But a moonsault makes sense and is a way to splash your torso on someone instead of just your elbow. A moonsault makes sense because it's just turning around in mid-air rather than turning around on the turnbuckle for a splash/senton.
