Faces paid APA to even the odds so they could fight on an even playing field, not the same thing A&8 have done, and that doesn't make sense considering the heels most of the faces are fighting are A&8s. Never mind that the A&8's goal is to hurt TNA.
Dillon was added to the Horsemen because he was already Tully's manager/advisory role during his feud with Rhodes & Baby Doll in a sensible spot. What role would Kash have when Roode and Bad Influence are way above him, never mind the idiocy of sticking those three with the likes of Robbie E and Gunner.
And yeah, shock heel turns have been done many times. Pretty much why TNA is in the rut it's been in over the past few years.
Kid Kash has always been one of the top talkers as a heel. Plus, last I remembered, Gunner and Kash was a team. If Gunner is put into a group headed by Bobby Roode, Kash would probably be in it as well.Managers are basically mouthpieces for the heels. They add dimensions to a heel's character as well. Honestly, did Tully really need Dillon? Absolutely not, but added something to Tully's heel run.
An Aces & Eights face turn would be logical under the right circumstances, not just something out of the blue. If Aces & Eights were feuding against TNA, then why have Roode and Aries paying them for their services? Really, they are being booked liked the APA did in WWE. And perhaps that is what it will eventually play out that someone has paid them to take out TNA's top wrestlers.
Adding Gunner and Robbie E to a heel group with Roode, Daniels, and Kazarian will help to build Gunner and especially Robbie E as top heels and to establish them as two of the top guys in TNA.
The reason TNA is in a rut is not shocking heel turns. It is bad booking. Same reason WCW did so poorly at the end. TNA creative never booked guys past a certain level. They've had performers who were ready to be top names in promotion. Yet, they weren't given an opportunity to do so. Same is going on now.
About shocking heel turns, if it is the right person at the right time, there's a possibility for some of the greatest feuds in TNA's history.
