I would rather The creators delete the whole C.A.W. system they have right now and go back to how they did things in No Mercy, have the player select a body type, face and clothes from a Wrestler in the game. or if not the whole thing, let them make a few custom body types the same way they made the characters in the game.
I don't mind if there are only 20 shirts, 20 pants or whatever to select, it's better than all the crappy parts they have now, they have imported parts from the last 3 games and with each import into the next game the quality of the tattoos and pictures have gone downhill they are all blocky and shit.
It would be awesome to place Edges coat or Bret Harts LEather Jacket on your created superstar when he make shis enterance, how about a good pair of jeans or leather pants like tajiri's.
Get rid of the whole voice over thing, it must have taken a long time for them to record and took up a lot of disk space not to mension the voice overs sounded so scripted. so scrap it.
Make half the shopzone something great instead of Bra and Panties for the women, I mean come on, We're not that into gaming

(same with all the female tops in C.A.W. who the hell makes women in underwear, sick freaks)
The story mode needs to be smooth without the feeling that it's looping, maybe something that starts off like you're only wrestling a match each week then judged by what you do (dirty moves or clean moves) the story will change into you wanting respect or whatever, have it random selected like that.
Have all the championships.
The Belts need to be cheaper or atleast increase with value quicker.( I played 100 matches with a championship and it only went up about 5 grand.)
More current superstars, more new moves and finishers from the indies, fairer move power (Styles Clash having only two blocks of power when it's better than the worm etc)
a new weapon select system where you can select which weapons you want to be able to grab from under the ring by selecting what you will grab via the C.A.W. menu (you know, like top of ring - table, left side of ring - ladder, right side of ring - chair, bottom side of ring- ladder etc)
more ladders and tables in TLC matches.
man what else... more custom taunts... take soemthing from RAW and use the whole create an enterance option, create a move option would be great and for online play let any match be selected instead of just a single match.
