A few weeks ago i saw an episode of Thorins Valorant talkshow and there they had a guest who is apperently very involved in the korean scene. They have talked about DRX´s chances to win an event, where thorin made a great point imo. (Thorin has been involved in the CS 1.6 scene and also lived in Korea for a while so i kinda trust him if it comes to these topics.)
Unless a game becomes a cultural phenomenon in Korea there will never be a scene developed enough to become dominant like in other games, since things either are very very niche in korea or cutural phenoms. Valorant hasn´t managed to become a cuturally accepted game, which is why he doubts that this will ever happen. Still, in these niche games you usually get a hand full of Koreans who become really dedicated in their craft, which are theoretically speaking on a world class level. Sadly for them, the practice they get in their region aint good enough to keep up with the other regions. What they do then is focussing on perfecting the early round game, which is obviously the most structured part of the round. The longer the round goes on tho, the less you can relly on protocols, which is usually the time where these teams fail. According to Thorin this has been a thing that already happened in CS 1.6, where the korean scene was not that big but you still had always a Korean team which was like in the top 8-12 range.
I strongly believe that this is what happens to DRX right now, and unless the Korean scene develops there is no way that they are going to win an event, since they will never be able to develop god tier late rounds if their region is so shiet.
