JuulDK, to answer all your questions:
First of all regarding the matches being short. They're much longer now. I don't like to bore people with tons and tons of paragraphs. I'd rather keep it in the middle of short and long. Not too short but not too long either. With Pay-Per-Views I'll go a little bit more in depth with the matches.
Opening Segment: I thought that people would get that there could potentially be a match later in the night. With the confrontation between Punk and Cena. A match seemed highly likely. I would have done that, but Stone Cold interfered. What I'm doing with Cena is for a reason, you'll just have to keep reading to find out why. I have something planned for him. Punk fleeing was to generate him heat. If Punk began to run away from Stone Cold in real life, he'd get major heat for it. Just building him more up as a heel really. That's what I wanted to accomplish. Stone Cold coming out and giving a Stunner to Punk would have made him look weaker.
I wanted to get the rematch clauses out of the way. I know that sounds strange but it left the field open for me then and I didn't have to stick to the rematch clauses. It would have turned out to be a very predictable PPV and I didn't want that.
Edge as GM was done because I've always wanted to see Edge as the GM. There may be something down the line for him and he may have an involvement in some storylines, keep watching for that.
Regarding the world title match, Ziggler uses the neckbreaker, mostly does it when swinging. I've already established about the matches being short. I'm improving that in later shows.
Regarding Undertaker and the streak match, keep reading. I'll be dropping hints along the way. I agree with you on the Shield segment, it didn't turn out how I'd planned and became cluttered. I probably rushed it and didn't think about it.
No, I established Reigns was the US Champion, he won it in June of 2013. It says it in the original post. Reigns was involved in the WrestleMania match and his title was being defended under a freebird rule.
Kaitlyn gets her rematch because of Paige causing a DQ early on. Read SmackDown and you'll see!
Keep watching Team Rhodes Scholars, I have plans for them. Keep reading on and you'll get what I mean!
The match ending with an emotionless Cena was done for a reason too. This is all leading to a huge Cena storyline down the line.
My matches get better through the shows and better laid out.
Thanks for the feedback. I hope you enjoy the other shows more! I'll definitely check yours out!
