Dude FaZe literally burnt mouz in last match. Also mouz lost to everyone recently, so 1 down.
Fnatic has lost it since Pro League, they couldn't make it out of groups in RtR. So, in recent form, FaZe is better than Fnatic. 2 down.
Do we even need to talk about NaVi? They literally got destroyed in RtR, 2-0'd by even VP and Hard Legion. They're nowhere near FaZe in current form. All down.
So basically, if we're looking to the current forms of those teams, FaZe is better compared to others.
