I agree, LCK casters for a long time have been super chill which I especially appreciated when I lived in NA and the games were on at midnight.
I think the crew there is amazing but I wanna shout out my LEC boys too cause they've gone through a big style change. Compared to a few years back Medivedi and Caedrel/drakos are just... funny?! idk i basically ghosted league last year except for the big matches and the duos have relaxed a ton (especially in regular season) and its really made me enjoy watching league again
