There are 16 slots in Champions.
10 slots are decided, for each region 3 slots directly via League, and 1 slot for Pacific LCQ winner.
6 slots remaining, I think Riot will divide for:
- 1 slot for EMEA LCQ winner
- 1 slot for Americas LCQ winner
- 2 slots for China (really don't like it, but that's possible. Riot loves China, therefore had given them 2 slots in Masters)
- 2 for an event, like as a global LCQ with 4 teams compete in:
- 3 from 4th place of EMEA, Americas, Pacific
- 1 from 3rd place of China (that's right, because Riot loves China).
