Pretty simple, allow some mod choice to play a map so that it's unranked but uses the current iteration of scorev2 instead of scorev1.
Why? A tournament I'm playing in uses scorev2 as their win condition, and the future implementation of scorev2 in future ranked maps means that in order to effectively practice these, I have to organize a multiplayer lobby. It'd be preferable to allow users to practice sliderhead accuracy, and the different score weighting system without needing to deal with the associated difficulties from playing in a multi lobby; people may not want to play scorev2 in a multi lobby, I'm unable to quick-retry maps that I wish to practice on scorev2, map choice is not isolated to a single person, and try as I may, there is still significant time wasted to map choices and waiting for other players to ready.
