Did Luminosity Gaming fell off?

Luminosity Gaming in the first major split proved to be really good for them as they didn't miss top 8 in any regional and they made top 2 in regional 2. Every other team other than GenG and G2 weren't able to do that. Luminosity also played really good at the major reaching round 5 of swiss, beating OG and going to game 5 with Vitality. However this all changed in major 2 open qualifier 4

In open qualifier 4, Luminosity fell off, they lost to Netherlamericanada 3-0 which was unexpected but I expected it to be an off series. After they beat TSM, I was relaxed and thought that they will be able to beat OG just like they did in the major. Then they lost to OG and that was very disappointing. They beat Moist which was great but then they were unlucky and played GenG which they lost 3-0.

The thing that makes me sad is that their losses weren't even close. None of them went to game 5. They lost a 3-0 against a top 14 team that lost every single game after they beat Luminosity. Against a top 8 team 3-1. And they lost against the eventual winners GenG. They really should be beating OG and especially Netherlamericanada. Now they got top 11 in open qualifier 4, their chances of qualifying to the major are greatly reduced unless they pop off in the next two qualifiers and make top 4 and top 8 which I don't think will happen.
