Each team is allowed to bring six players (five starters and one substitute) and one coach that accompanies the team onstage during the drafting phase. Most of the rosters were straightforward, but the decision was interesting for two Korean teams in particular: SKT and Longzhu Gaming.
SKT used two subs liberally throughout the summer split: Park “Untara” Eui-jin and Kang “Blank” Sun-gu. Untara had a better win rate than Huni, but SKT elected to bring only Huni for the top lane and used its sub position for more jungle security in Blank.
Worlds begins Saturday with the play-in stage. The top four teams from the 12-team play-in stage will join the remaining 12 teams to comprise a 16-team group stage. The tournament runs through the first week of November.
