As you know, this server is oriented to support bunch of clients from a range of 2007-2015 years. But server also supports client modding so you can implement some features in your clients, and one of these can be rate adjust from lazer. Main issue of supporting this feature is that unmodded clients doesn't supports replays with unknown mods and attempt to show score with uncommon mods could break leaderboard. Honestly, I didn't checked how older clients shows scores with unimplemented mods, but if client would try to show then leaderboard won't load online scoring. So if devs would theoretically implement rate adjust and add pp farming for it then they might add some flags to prevent score retrieve for a clients without rate adjust mod. What do you think?
