Context: It was game 3 of worlds Quarterfinals with a base race to decide KT's fate, watch the ending [here].
I believe that there were rumors at the time saying that he was subbed out due to tilt, but the real reason has been revealed by the man himself!

TheShy answered why he got swapped out at the 4th game of kt vs iG, because coach Kim wanted him to play another champion but he insisted on play Fiora, so after game 4 he got subbed out per coach's request. ELLEMEN asked him would he choose Fiora if come again, he said yes.
