Masters - Copenhagen

Since Masters 2 will only have 12 teams, what do you think is the best format fitting for the number of teams riot choose.
Is a swiss format good? or MSI format with round-robin groups ? or something else.
I think that any other format besides the one used in Masters 1 is better.

the same format from last masters woudl be good

round robin will be better.
i dont want better seed and that bs
