Sentinels vs 100t
EU just seems outdated compared to NA but they are all cracked players and honestly EU people are better aimers than NA but the way they play are a lil sloppy compared to NA(I could be VERY wrong).
Sentinels - They went undefeated in Iceland Lan and adapts very fast ingame and the only problem I see is when they get to 11 or 12 rounds they start choking and give the other team rounds
100t - Lan experience, strong mental and bringing back games that are 3-9 half or 2-10 half to winning it or bringing it very close which that momentum carries onto the next couple games. The only problem I see is the lack of Astra use and their comp is all over the place sometimes.
I have an open mind though so I'm not dead set on anything these are just my thoughts.
edit: I don't think Envy will make it to far just because of their contact style play which I think can be countered on lan compared to the composure that teams like Sentinels,100t, Gambit, and G2 have.
