Ok yes those are very true. Weapons should do more damage. As should putting someone through a hell is a cell. The music is annoying at parts. Pyro would be nice. I don\'t really mind if they walk down the ramp or not.
In-crowd fighting would be nice. Signs don\'t really matter. The crowd already does cheer, but chants would be nice(SLUT! SLUT! SLUT!) Announcing would be cool as hell but only as long as it isn\'t the same thing over and over. Royal Rumble is fine as it is but more moves should throw people over(suplex, chokeslam)
All of those things would be nice but none of them(except the weapon damage) have anything to do with the game engine.
It would be funny though to have King and JR sitting at the announce tables and you could go over to them and put them through a table if they said something bad about you.
To add to that list I would say:
All moves can put people through a table(suplex, rock bottom, olympic slam, pedigree, chokeslam)
