Whilst this is welcomed, I have a number of suggestions which might help make this better (apart from just more dislikes, likes)
Have BR presets - I might not want Stalingrad maps to be a like on BR5, but in low / medium, BR4 even I do.
The same can be applied to low BR, where I might want Tunisia to be my preferred map and not somewhere else.
If this is too much work, allow me to have a button to immediately reset my preferences back to none, so I can chose my preferences based on my current BR.
Feel free to discuss below, stay on topic and try to be nice to each other
