I think the ideas presented are intriguing, but I am concerned about the current player base for ladder and TMM. The number of people who play these modes is already quite low, and implementing features that allow players to choose which kind of map style they want to play could potentially harm the already small minority of players.
However, I do see potential for these ideas in the future. As the game evolves and attracts more players, these features could become more viable and beneficial. But for now, given the state of the game and its player base, I am not entirely convinced that implementing these features would be the best course of action.
