Ex optic aka nrg now has like a 30 percent scrim win rate. They don't play to win scrim, they usually working on improving certain aspect of their play or comps.
Bro lev was owning in scrims, it doesnt mean shit. It means that tsm tries their best to win and nrg testing, it shows to nrg what they are doing is not good if it doesnt work on a t2 team
NRG/Optic core is pretty famous for losing in scrims since Iceland. It doesn't really matter imo since they always get results no matter what when it's game time
