Florescent last act is pretty close in terms of stats, not rr though he only managed to get 1000 rr in 48 hours, since he probs don't have that much time to play ranked (preparing for GC)

Edit: now that I think about it again bro might be insane 💀, that little hours of playtime and reaching 1000 rr....

Edit2: OXY is also insane in terms of stats
