Actually they have pretty decent chemestry between Olof, Guardian, Niko and Rain. And we already know that Adren is 100% getting dropped because his trial period didn't go as they wanted it to go.
Now i hope Niko decides to put his ego to the side and they get a GOOD IGL that can lead them. The reason Niko can't IGL is not that his strats suck or anything, it's just that when he gets tilted (which he gets every time he plays badly) he makes bad calls which is why faze often loose to comebacks. Because as soon as they start losing Niko gets tilted and stops thinking about the calls.
