Again, there are far more people who criticize him than praise him. I see this on every TL match thread, especially considering S2k is usually at the bottom of the scoreboard.
I am mystified at your claim that people say S2k took TL from nothing to top-1. I haven't seen anyone say this with any seriousness. Is he a catalyst to their jump from #2 to #1? Absolutely. If you can't see that, then this argument is pointless.
Whether or not Astralis is in a slump is irrelevant. Time and time again, I see excuse after excuse being made for EU teams. I used to see the same tired excuses about how EU teams were slumping when SK had their run in 2016. At some point you need to start crediting the top team for having consistency in any given year, considering the quality of CS that exists nowadays.
