Nsi is a pro minecraft/League of Legends/Rocket League aaaand CS:GO player.
Rumuor has that he even teached players like Faker on league but when the community needed him the most he vanished. Only if a player is at least top 5 in all the games from the above he can truly call himself as good as NSI>
1: Did you know that NSI teached faker in season 2?
2: Isn't NSI the same dude that disappeared all those years ago?
1: Yeah, such a shame
