Yeah it's hard to know. Both c9 and g2 have inconsistent results so it's hard to tell but G2 has improved, shox roams free and they won 5 games in a row and are ranked first of thr groupstage, ahead of FaZe. Besides G2, only FaZe and SK weren't disappointing in this major.
I believe that, statistically, the G2-former nV group always got good results in playoffs after finishing first in groupstage during majors so that's what I'm hoping will happen.
No team is to be underestimated, SmithZz said it himself. I'm feeling confident about this, fighting C9 and later on SK is better than fighting Na'Vi and FaZe imo because of the different styles and from what I remember, G2 tends to be that sort of anti-SK force.
Fingers crossed it will go as I think, but statistics and momentum aren't everything.
