LAST GEN (PS3 and X-Box 360)
+Same Roster of Characters as this time, plus more (Curtis Axel, Tamina, Xavier Woods, The Usos, The Wyatt's, maybe former divas along with more legends, etc. If, for instance, CM Punk and Kaitlyn are reduced to DLC, I'll understand so long as they eventually end up somewhere).
+Update entrances, attires, and move-sets as needed (Superstars and Divas don't need duplicate Finishers and Signatures [One superstar/diva defaulted to have the same move in both Finisher or Signature slots]. Also, as just two examples, Daniel Bryan and AJ Lee have evolved their movesets over the years).
+More options for Superstar Heads (One or two Divas included in Superstar Heads wouldn't hurt).
+More Superstars/Divas with COMBACK moves
+More OMG Moments.
+Include ADVANCED CUSTOMIZATION option for Champion Entrances (Championship Entrances seem more important to me than Regular Entrances, yet only Regular Entrances can have advanced Customization).
+For TAG TEAMs with multiple partners, different tag team entrances (If two superstars enter together, that's one entrance; if it's a superstar and a diva for a MIXED TAG MATCH, it's another).
+Fix Rivalry Manger in Universe Mode
+Add to Universe Mode
+Extended library of match type options (Off of the top of my head, I can only think of the example of "AMBULANCE" match. I know that there are more).
+RETURN OF GM MODE!
+Add more options to Creation Suite all around (More attires for CAWs, more moves in Create-a-Moveset, more Options in Story Mode, Ability to Create Submission and Grounded moves along with Standing, Corner, and Top Rope, etc).
+Keep 150 available CAW Slots
+Superstar Heads takes up one of three attire slots instead of a CAW Slot (If chosen as an alternate attire).
+Faster load times.
+Honestly, PLAYTEST THE GAME TO MAKE SURE THAT IT WORKS PROPERLY (No freezing, commentary glitches, move glitches, black outs at the end of the match forcing a reset, etc.)
+FIX the glitch that defaults Created Teams, Superstars and Movesets every time new content is downloaded.
CURRENT GEN (PS4, X-BOX ONE).
Obviously all of the advice from above (especially the return of GM Mode if not for both generation consoles, then at least for next gen). PLUS:
+Even more options all around for Creation Suite
+200 available CAW Slots
+Even more match type options.
+Even faster load times.
+Every Superstar/Diva has the Superstar/Diva Heads Option (again, that would take up an attire slot rather than a CAW Slot
+Add CenaFanatic's idea of Storyline Manager along with Rivalry Manager under Universe Mode (Sorry for stealing ideas; I thought that his happened to be awesome as it was).
Its actually possible on new gen. Im sure we will get more people in the ring!
