Reigns character and Wrestlemania title shots

Do people realize they also mimic Hogan's runs on top of WWF and WCW in the 80s/90s? Only wanting to defend the title at certain big shows (never on SD), threatening and blackmailing authority figures to keep the top spot (Pearce), holding younger fresher talent down (Jey) etc

Also, with EC matches for WM title shots for both Universal and WWE title, how does Edge's WM title shot fit in there? Three way dance? NXT title match?

The RAW side is for the title itself so I imagine that leaves Edge to challenge Reigns, doesn't it?
