Probably because Punk was feuding Kane at the time.Daniel Bryan was on fire when CM Punk was still there how are you forgetting that?...
Really?...:reigns3Punk returning, even if it's just for a short run, does nobody big favors.
WWE product is ice cold, Punk is most likely not going to bring ratings through the roof, it would only serve his bitter haters as more fodder against him, plus Vince would need to pay him a shitload of money.
Also, it would lose Punk credibility. I still have the highest respect for him.
And as far as I know, Punk sells his own merch, he really doesn't need WWE.

Because his criticism was of part-timers hogging Mania main events, I only see him accepting this spot if he comes back for a Jericho-like full-time run for at least a year straight. A part-time return where he's offered the main event in kayfabe but insists that a full-timer main event and offers to wrestle the kickoff match could be a fun way to follow up the CM Punk narrative, if he has to be part time.We all know Punk still wants that Wrestlemania main event. If it was offered to him, I am sure he would take it, you can't just switch of your lifelong ambition.
