I feel he should have continued being in a program with Gable since those two were actually putting on some great matches.
You know how he attacked Gable after HIAC? They could have had Corbin paying people to go with the whole Shorty G bullshyt, explaining why all of a sudden people like Kayla were calling him that and why his match graphic said it too. Could have had Gable not embracing it at all and just wanting to get his hands on Corbin. Could have extended the fukk out of it if they wanted to desperately give Roode/Ziggler something and had them as obstacles Gable would have to get through to get to Corbin. Have Corbin pretty much involve himself in any of Gable's matches, causing him to lose or beating the fukk out of him after a win. Have Gable cut the whitemeat babyface promos he is actually decent at. Have Corbin's attacks get more violent so instead of just being a dikkhead, he is just straight up unlikeable.
But instead of that, they kill all of Shorty G's heat with the stupid gimmick and putting him in a nowhere feud with Sheamus. Corbin is sitting in limbo because he actually isn't gaining anything from the Roman feud since he loses pretty much every big match because its against Roman.
