In the past, yes, no one was good enough. Right now? That's bs, since he just wants to leave the IGL role but there are no IGL rn, and in 2 weeks there'll be another important tournament.
And AdreN sucked as Igl, so is obvious. People has to stop thinking of Niko as the same person like he was 1-2 years ago, he suffered a lot thx to his ego and now he changed and that can be seen with today's action where he donated to a charity because he owed money, and even apologized. His ego is broken.
