WWE's Retribution faction already look like the world's first wrestling mash-up of Slipknot and forgotten nu-metallers Mushroomhead. You could probs throw a little bit of Demolition and (grappling's fave inspiration) Mad Max into that mix too.
WWE must minimise the stable's input this weekend - they've got other acts that badly need attention anyway, and it might be wise to focus more on feuds like Drew McIntyre vs. Randy Orton, Roman Reigns vs. everyone in his path and Bayley vs. Sasha Banks. It's crucial that the company make the right decisions when it comes to those characters.
Clash Of Champions is the least-important pay-per-view since Payback, but it needn't be an outright miss with senseless title changes, bouts that'd feel more at home on house shows (remember them?) or dodgy finishes.
