LOL astralis are still the same wtf are you on about? Sure, they played half-poorly the first couple of maps in this event but against fnatic they played very good actually. MiBR are much better individually than fnatic. Your opinion that they're laughable wont change that fact.
You only say things like "xizt can't adapt well" but you have nothing at all to support that claim. And the 14-16, 16-12, 17-19 map scores certainly doesn't help you at all LOL. fnatic looked sharp on the few online matches they played and now they've proved themselves further. You can't really blame anything on lack of data because KRIMZ and JW is at the core of the team and they've continued to play their usual game.
All well-performing cs teams in history except FaZe have had a top-tier IGL that isn't necessarily fragging. If you think Xizt was a bad IGL against astralis then you basically say that any lineup of 5 very skilled pug-heroes could beat astralis and that is non-sensical, considering Astralis is a team tailored to punish and counter teams relying on pure aim. You don't go 47:47 rounds against a team like that.
