Fnatic is an interesting matchup, a good result is more or less ideal for rates. Frankly, both teams have all chances to win, but who they will use more wisely is another question. Recall the recent events: Fnatic break all persons, including them managed to do yesterday (against ex-TSM), and NiP all trying to bring back good old TOP shape, but as long as it is not 100% the older get. Yes, although the chances are almost equal, do not want to put on such a terrible factor, but, unfortunately, it will remain so, according to assumptions.
Summary: low on Fnatic.
