It's been less than 3 hours, and with a time that's multiple seconds below AT, I am in the bottom 80% of players. One can say that I'm just salty because skill issue, and yes, partially, I am. But the guidelines requiring players to slow down their ATs only to have second barrier after second barrier beyond the AT being broken in less than 5 minutes is just stupid. Even if a new player gets AT, they immediately know they're nowhere near a good time, so what's the point of just lowering the skill ceiling so badly that there is absolutely no sense of achievement in having all official medals?
Edit: A few more attempts in, I've reduced my PB by another 2 seconds and I'm still significantly far from a good ranking. The times are genuinely insanely lower than AT for no reason. At least let the players know what a good time is, make the real ATs visible or something. Add another medal, or something!!!
Edit 2: As some of the commentors mentioned, for most maps, you can get an idea of how difficult it is based on AT, but that also then means that if the author doesn't know a trick or something then the AT is once again meaningless. As AdAffectionate says, there needs to be an overhaul. While hiding the entire leaderboard, not just times seems a bit much (although it would actually be a great system imo), perhaps Nadeo could just do what the community figured out a long time ago, and just add another tier of medal. The players from BIG, Wirtual and others have also mentioned on stream that it would be an effective way to make ATs worthwhile while also adding something more achievable in the middle of gold and AT, which can the be used for things like WS time guidelines and the like. Hell, even just making a standardised introduction campaign and using a new player's performance in that as the basis for SBMM could go a long way in improving both matchmaking and also make filtering maps easier.
