I prefer clear rule for wild card which would be valid in long term. I can imagine some:
- best wold rank team which is not qualified (by league, cup, previous B3 win rules)
- best team in last season B3 which is not qualified (if there is a tie between semifinalists, quarterfinalists etc., group play rank would be a decider)
- best ranked team in last season B3 Group Play which is not qualified
- best ranked team in last season B3 Group Play which is not qualified, but just teams which were not qualified for Knockout (rank #33 and lower)
And I hope someone can think of some other.
