As a long time Seth hater even in the IWA Mid South days, and a long time Roman mark, I think it's time to either end or at least pause Roman's THE GUY push and give it to Seth for the time being. He's got the juice from the crowd, the swagger in his step, and is on fire in the ring. There was a time when Roman had at least 2 of the 3 of those, but that time isn't now, and this angle with Brock specifically is dog shyt.
Let Seth be the one to beat Brock, maybe at Summerslam. From there you can put Roman a little lower in the card, have him beat Seth, send him to Smackdown where he has more opponents he hasn't met up with much or at all and you could give him an actual title reign, or you can use Seth beating Brock as the impetus for the heel turn if they ever want to pull the trigger on that.
Hate myself for saying any of this and I'll deny it in a month
