Firstly I would fire majority of the Creative team, and I would hire comic book writers as them guys are freakin' genius' and can write story-arcs months in advance.
I would go back to having brand splits and a 3 Brand company. #1 Raw, #2 Smackdown, #3 NXT (NXT been like the ECW) This gives all 3 brands good solid rosters which would be able to produce good shows for network TV.
I would have a roster limit of 25 people per roster, I would bring back The Hardcore Title, Women's title (2 Women's titles), Tag team championships, and I would also bring back the cruiser weight title.
My show would be TV-14 therefore there would be plenty of blood, and occasional swearing. I would cut all ties with the PG market bringing and end to shows such like Saturday Morning Slam.
I would have JBL, and Michael Cole as the Raw commentary team, and Josh Mathews, and William Regal on Smackdown whilst Jerry Lawler and Scott Stanford would do NXT.
I would try to employ a few wrestlers most notably Jeff Hardy, Kevin Steen, and Samoa Joe.
I would also re-instate the WWE annual draft which would shake up the rosters a little bit.
