Bron and Bronson together is more than straight. But I don't think adding Seth to the mix suddenly puts it over the top, as it's fairly common knowledge on WWE programming that Bron is most likely to be the future of the company, and all Bronson does is fukk people up. If anything, this almost impedes their respective rises.
I still believe what Heyman should have done was recreate his own Dangerous Alliance. Having it centered around Bron and Bronson would have been dope, as Heyman would be guiding and ultimately using the future of the business for his own gain to punish WWE for what he perceives as disrespect, the tipping point of that being him having to choose between Punk and Reigns while Rollins toyed around with him during the buildup.
