I'm sorry I have to make this complaint, but I do.
jump_serenity is clearly a jurf map, which is fine if you like jurf, but in the showcase it pretends that it's not a jurf map even though doing the jurf strats is, in my opinion, easier than doing the jumps. The result of this is that is that to get a participation medal you need a run that's faster than 2:45, which is very easy, and that is fine if you want a lot of people to participate. But compare this to the other beginnings maps; the top 50 online runs alone on serenity are all less than 1min, while to get less than showcase time on lithium and thus a participation medal you need to be in the top 25 (of current online runs). On obelisk the only online run that's faster than showcase is wr, and the situation is similar for the other 3 maps. I do not find this fair to jumpers who want to do just the demo maps or jumpers who don't much care for jurf maps (maybe just me), since participation medals are made a commodity by jump_serenity.
What I'm complaining about is that its too easy to get a participation medal from jump_serenity than to get it from other maps. I've heard that maybe the time requirement will be dropped for stage 3 maps or maybe there is a solution already being thought up. But as it stands I don't feel motivated to submit a run since I know most anyone who runs serenity will get a medal of participation easily while anyone running on any other map will have a much harder time getting a participation medal, and I've also heard that the spreadsheets aren't public.
