i accidentally put this in the wrong one. Would it be fair to ban non-community made maps from speedrun categories?

What do you mean, why would the mods ban actual maps

True

I'm asking this because a map like Forsaken Falls has no powercube boxes, making players fight each other for powercubes, ultimately making the game shorter, where as something like Acid Lakes has powercube boxes near the players, making the players grab those first, making it a little longer

Well, it's the player's choice to choose which map.

Yeah, if people want, they can wait until Forsaken Falls comes around again
