More important than luck, it's about momentum. And I think Navi was really on fire and had pretty good momentum. It's sad for flamie but b1t is currently playing way better than him in Navi.

Speaking of momentum, It could be over now for Navi and I do think Gambit are still able to beat Navi in another match. Or maybe not 

Anyway, it's a good series with an unexpected result. GG
