Astralis also continued to not win shit after IEM 11 due to being denied 3 times by FaZe at Starladder, IEM Sydney, and ELEAGUE Premier.
Let's also keep in mind the major was weak af due to the major champions SK playing 4v5, and every other team was weak since this was karrigans first major with this team, but with the same lineup after the major they got 4 finals and 1 title whilst Astralis got 2 finals and 1 title in the same timespan.
If you want to count the +GuardiaN +olof FaZe too, then they went 17-0 and won 2 tier 1 events in a row. Astralis could never ever do that, and karrigan was massively pulling his weight tactically, which is CLEARLY shown in his leadership, and in his map picks.
If you think for a second that any other IGL apart from probably FalleN could pull together 4 players who once had a claim on best player in the world then you're demented.
