I'm glad Rollins is back, but his return is really more of a Summerslam Main Event, not two secondary PPVs and then Brock.
Reigns plays off chaos very well as he did with The Shield. As we saw with HHH, he's not going to amaze you with mat wrestling, but he is great at the chaotic WWE style. So, keep it up with the right opponents and circumstances and it can be great.
Side note: They better figure out how to handle the Brock thing because no fucking way did you just build this guy up for 2 years as indestructible and then go feeding him to Reigns with what is probably a 3 week build. Brock is a Wrestlemania guy for Reigns, because once he loses then he goes back to being just another guy.
