#2 CM Punk would have won more World Championships
As stated in the last slide, there would have been an excellent chance that CM Punk would have added to his World Championship tally as soon as WrestleMania 30.
Whether that would have occurred or not, what is unmistakable is that Punk would have added more titles to his resume in the four and a half years since his departure.
Men like Bray Wyatt, Jinder Mahal, Kevin Owens, Finn Balor and Dean Ambrose have all reigned as Champion in the years following Punk's departure. It seems highly unlikely that all of these men would have been World Champion had Punk remained with the company. Punk could easily have been inserted into any of these men's title feuds as he was and is a much bigger star and legitimate Champion.
Punk's presence in WWE would also probably have saved its audience from witnessing epic Brock Lesnar title reigns with minimal defences.
Punk's five World title reigns would have greatly expanded to at least 10, without question.
