'Worlds' is all about the Meta Shift. The patch played at Worlds is different from the Summer Playoffs. Korean (LCK) and Chinese (LPL) teams are historically superior to Western (LEC/LCS) teams. Do not bet on Western teams to beat Eastern teams in best-of-5 series; the skill gap in 'macro play' is too wide. 'First Blood' and 'First Tower' are volatile markets; 'Match Winner' and 'Map Handicap' (-1.5) are safer plays on LCK/LPL favorites.
Esports contests are shaped by patch changes, map or character pools and how well a roster prepares specific strategies. Series format matters a lot, since a single game is volatile while longer series let the stronger side correct course. Dense online schedules, travel to offline events and roster changes affect consistency. Interest usually sits on map handicaps, total maps, in game objective markets and correct series score.
