I think we should wait a little with all of the Cena dream matches - Strowman, Reigns, Joe etc.. Keep them for bigger PPV's (Reigns or Joe possibly for WM34)
I also hope that the whole Balor vs Wyatt feud is done - because as much as I love these 2 workers, it is really bad.
I think the card should look as follows:
Universal Title Match
Brock Lesnar (C) vs Braun Strowman
No Disqualification Match to determinate the No.1 Contender for the WWE Universal Championship
Roman Reigns vs Samoa Joe
Singles Match
John Cena vs Finn Balor
Steel Cage Match for the WWE Raw Womens Championship
Sasha Banks (C) vs Alexa Bliss
Singles Match for the WWE Intercontinental Championship
The Miz (C) vs Jason Jordan
Triple Tag Team Match for the WWE Tag Team Championship
Dean Ambrose and Seth Rollins (C) vs The Hardy Boys vs Sheamus and Cesaro
Bray Wyatt should be facing someone new who will be moved after the superstar shake up or instead fill in for a superstar who is moved to the SmackDown brand (possibly Finn Balor - but if that's the case we will need to do a different card structure as we have seen Wyatt vs Cena enought already).
This is perhaps how the card will be and ought to be. It only leaves out Bray Wyatt, and that is fine.
The card I suggested was too good for No Mercy, with a dream match like John Cena vs Samoa Joe.
The triple threat ladder match is likely to happen, and seeing how it's three strong teams battling for supremacy on Raw, they should remain entangled for a while, and have ladder matches and cage matches, sort of like Hardys, Edge and Christian and Dudleys.
As for Finn Balor, I feel like I have no interest in anything about him, any of his feuds, and I don't care for Bray Wyatt either.
But still, I think he has nothing to gain from a feud with John Cena, not at this stage at any rate.
To begin with, he's a cruiserweight, too tiny and too skinny to be taken seriously, isn't glorious on the mic, doesn't have a character, and just comes across as cold and boring. Sort of like Chris Benoit, except that Benoit was so intense with his chops and suplexes, a superb technical wrestler, and certainly a heavyweight at 220 lbs.
Secondly, if he loses to John Cena, what does he gain? On the other hand, even if he wins a match against John Cena, a random match on a PPV, it isn't going to make him a huge star(owing to the fact that he is cold and boring and uninspiring) .
And if John Cena puts him 'over', how does it make anyone else on the roster great? John Cena put AJ Styles over, and he'll certainly put Samoa Joe over, and we would love to see that, to see Joe make him submit, and pin him.
But would it be a valuable victory for Joe(as it was for AJ Styles) if John Cena were to just put every one over, like Finn Balor?
So you see, he ought to stay away from Balor.
I don't mind seeing John Cena vs Samoa Joe in a series of matches as of now, because that'll lead us to Wrestlemania, where he could be facing Roman Reigns.
I think even as a full-timer(which he is not), John Cena would need a year to have feuds with Joe, Roman, Dean Ambrose(which I want to see, especially a heel Dean Ambrose), and Seth Rollins, and there's still Braun Strowman.
He shouldn't rekindle his feuds with Miz and Wyatt certainly, and also not feud with Balor.
The aforementioned 4 in Joe, Roman, Ambrose and Rollins should keep him occupied, as well as Strowman, and there's always someone from SDL, considering John being a "Free Agent".
