IG is really trash right now, perhaps after winning a major they want to relax a bit. After watching their series against Aster, I think betting on them is a very risky decision in the near future. And don't forget they were also struggling against Magma before.
I don't think IG is trash, during that series they had a good laning stage it's just that their drafting isn't the best after the new patch while Aster drafted really well around their comfort heroes. Even before the DPC IG always have that inconsistency or volatile trait but they seem to show up on games that matter.
Here's my early bet for later
G2 to win @1.91 vs Faze.
G2 with the better form and Faze still struggling even though they won vs Furia it's still not enough for me to back them on this series.
