I've been watching competitive Valorant since the game was released, and I've seen most of the matches from Korean teams. It's always been a region I enjoy watching because they play a more pragmatic style of Valorant, focused on ability combos.
The problem is that they have a reputation as chokers because that's exactly what they are (except for Masters 2 last year). Every team gets big leads when playing in the playoffs, but their mental fortitude fails, and they throw the matches. Either that, or they enter the game completely in shock and get swept without putting up any resistance against their opponents.
Isn't it time for Korean teams to invest in an effective team of psychologists?
I remember Astralis in 2016–2017 went through this exact problem, and we all know the result of hiring a good psychologist.
