Why are there so many people overhyping Choi Ji-man?

They talk as if it's obvious that someone with a career MLB WAR of 4.4 is better than the KBO legends lol.
You need to hit at least a career MLB WAR of 10
to truly say that player's entire career was at a Major Leaguer level.
If it's below that, it's only right to look at it combined with their KBO WAR.
No matter how I look at it, a player who surpassed a career WAR of 60 in the KBO
seems greater than someone with a measly career MLB WAR of 4.4.
