You can say the same thing about Wyatt in the same feud, sadly. The main difference between them is Wyatt was a better talker and Harper fit into the intimidating lackey role better then almost anyone ever. But really, they botched just the entire Wyatt family thing from everything post Elimination Chamber against he Shield on. It’s so easy to write the Wyatts as a creepy cult. Have them run of with guys and have them come back as more Wyatt members. If a guy is leaving the company have the Wyatts assault him and have him never be seen again. Then have a member gain a conscious and turn leading to a Wyatt war.
But, yeah, the end point for Harper and Wyatt was the Orton feud. Harper should have been in the Triple Threat, and Wyatt should have pinned Orton, and continued into Wyatt/Harper singles after that. Instead we got an Orton title run just for him to lose to mother fucking Mihal.
