Over the course of the last three decades, factions have been a key part of professional wrestling. In WWE, factions created a common goal and a sense of comradery amongst those involved. For all the names and faces tied to pro wrestling's many factions, several have been notable.However, while a number of stables have been successful a number of them have failed, leading to a reliance on nostalgia and the past. For every group fans love to remember like D-Generation X there are those they may have forgotten like the Truth Commission. Today the WWE has factions like Seth Rollins' Disciples and The Hurt Business, led by MVP.My suits actually fit and don't stop several inches ABOVE my ankles.🤷🏾‍♂️ https://t.co/lm5jvvPNRG— MVP (@The305MVP) July 30, 2020However, who in WWE would be the best fit in a faction? Taking it a step further, which factions should be brought back? There were a number of dominant groups that managed to take over the wrestling world both in and out of WWE.However, despite being successful at their respective times there is no confirmation that they will be this time around. Several things play a part in whether or not a faction will be successful if they are brought back. Sometimes, there's an interesting twist that can be added to a classic story to make it seem like new. Sometimes it's best to leave things in the past. Here, we'll be looking at three factions that WWE should bring back and three that should be left to be enjoyed solely on the WWE Network.#6 WWE factions that should: LegacyWith Orton in this same role there are other second or third generation wrestlers that could fill that role today. Photo / Sky SportsOf all the WWE factions the company has promoted over the years there was one that was an intriguing option to recreate, the Randy Orton-led Legacy. For those unaware, Legacy consisted of three second- or third-generation wrestlers in Ted DiBiase Jr, Cody Rhodes, and Randy Orton.The group even seemed to toy with the idea of having as many as five members with the son of the late Jimmy Snuka, Sim Snuka, and the son of Afa of the Wild Samoan's, Manu. While the faction only remained as three members there could have been as many as five in the group in its time.The possibility of recreating this WWE faction concept could work with present second- and third-generation wrestlers such as Angel Garza and Andrade with Randy Orton at the helm. #MondayNightZelina isn't over.@Zelina_VegaWWE @AndradeCienWWE & @AngelGarzaWwe join the #RAWTalk set RIGHT NOW! pic.twitter.com/POWNX40htT— WWE Network (@WWENetwork) July 28, 2020This time around we have a bona fide mouthpiece in Orton whose English is much stronger than his teammates'. Whether or not this comes to fruition it would certainly be something to the WWE should explore.
