If the goal is simply to swap gamemodes, I also don't agree about the idea too much.
But let's pretend for a sec that you want to make a "specially flavored" version of an existing map...
You see I played Dustbowl with a cart and I quite liked it. Many things were changed too like holes in houses that weren't there before, opened walls, new paths...etc...
Not sure, though, if the map was still balanced.
I don't know if people want modified Valve maps more than new maps, but let's say I type in what I'd want changed or new in these maps:
- New weather condition which could bring new challenges with it like, snowy badwater where there could be snow banks blocking the cart that needs to get shot to push the cart further, slippery ice at some places, fog and snow falling that would make the job difficult for snipers and force them to get close and personal more often. Wind that would make rocket/sticky jumping more difficult.
- Night time Goldrush (not pitch black) lit only by a subtle moon light where the lights are all turned off in the map, except the one in your spawn, then you must progress and push the cart in the dark. The attacking team could light up torches or switch on a circuit panels so the team can see further. This could spawn health and ammo around the newly turned on lights. NO ammo and health on the dark sections so the defending team has a disadvantage there.
All this without changing the core layout and structure of the map.
Things like that.
