#2 Have Drew McIntyre betray Dolph Ziggler

Dolph Ziggler talked a lot of smack throughout the entirety of the Best in the World tournament, and while McIntyre stood there in support of him every step of the way, one can't imagine that going on much longer. Interestingly enough, with McIntyre and Strowman set to feud soon, WWE will probably make this decision sooner rather than later.
How WWE decides to do this is up to them, but they should probably center it around McIntyre getting tired of being Ziggler's lackey, and wanting to show how superior he is. This way, WWE could set up a match between the two at Survivor Series, McIntyre should get a clean win and then go on to a title match with Strowman for the big red belt.
Of course WWE could always decide to keep these two together for a while, and maybe even have the two men join The Authority, but McIntyre would work so much better as a solo act. In fact, putting him with The Authority might end up hurting McIntyre if he continues taking orders from someone else, which isn't a great way to build a top heel.
