Instead of making a quarter-finals style where #1 seed for a group play the #4 seed of another, they decided give a bye to #1 seed and make #4 seed go directly to Lowers.
While this only removes 2 matches from the total, which doesnt free that much space in schedule ( and its not like teams play a lot), It makes so teams that get 1st Seed in groups can just win 1 match in playoffs and go to Masters Toronto.
Lets take EMEA as an example, suppose group Omega ends this way after resolving ties:
1.Liquid 3-2
2.KC 3-2
3.KOI 2-3
4.FUT 2-3
5.BBL 2-3
6.M8 2-3
Than at playoffs we have Fnatic #2 form Alpha against KOI #3 seed from OMEGA, KOI upsets, winners face Liquid #1 seed from OMEGA.
Liquid could make another event by beating KOI 2x, BBL and M8.
ps: assuming the playoff format is the same as americas
