Change to map offerings
It had occurred to me that something that could balance the map offerings and, at the same time, make them more useful would be to add three offerings that prevent the possibility of being sent to small, medium, and large maps, respectively; in addition to adding another that cancels any of the other three offerings. This would mean that if the killer doesn't want to go to a huge map by using a low-mobility character, and if the survivors don't want to suffer on a small stealth map, neither would have to suffer, and it would be balanced. They could even eliminate the current map offerings (which are rarely used) and stop adding new ones (if people want to try a new map, it could become a separate game mode, like in FNAF).

Just add a second offering slot designed exclusively for maps so that you can at least narrow the map down to 5 options each game with a mostly even split depending on what people and the killer will always have a 20% chance or higher to get his map of choice
What I see as wrong with this is that it would simply repeat what's happening right now: someone puts in the map they want to go to, just because they like it, and someone else, tired of going to bad maps, makes an offer to cancel any map, making it all pointless. And what I'm proposing is intended to make everyone play on an intermediate map.
