Movable bullpens has been probably the #1 ask since SC's inception and it's been ignored time and time again for stupid props nobody uses.
Apply the trim code they have for the ground to the walls to eliminate props entering the field of play. Not sure why they made the prop the "hard" object and not the wall
Modern seats, and no I don't mean what they have now. I would like to see 90 degree corner stands like you see in most newer stadiums
Better suite levels
5)Expanded memory
Building block props...simple things like smaller blocks of seating, think like the minor league size but without the stupid suite-boxes on the top. Stairway options for the regular size ground level seating.
More realistic dimension templates, for example the completely rounded dimensions of the "county" style stadiums (Cleveland Muni, Milwaukee County, etc). OR let us have some sort of "allowance" with adjusting the walls...let us play with the height, and a total movement in or out of 20 feet before it becomes ineligible for online play.
No more "no-go" red flash of doom zones. So dumb that it couldn't be coded correctly...those no go zones creating so much awkward empty space. It also causes problems with props, which aren't anywhere near the field of play, to cause the error "Cannot place prop on the field"
