I took a stab at it :D
Looks like Fnatic, LG and Kungarna are all guaranteed to qualify
Liquid can only miss out if NRG win in the final vs IMT - they need LG to beat IMT
If NRG lose in the final against LG but IMT win the bronze match, then NRG are out and IMT go through
If IMT lose that bronze match then tiebreaker criteria applied
IMT can only miss out on qualification if NRG make it to the final - they need Fnatic to beat NRG
