opinions on current grand finals not having any map advantage.
NA Masters format is stupid. Now Faze will probably smash the winner of Gen.G-Envy, and it will go over again SEN-Faze. No real advantage given to SEN for winning upper bracket final.
There should be double elimination groups and then single elimination playoffs, just like in Europe, Turkey, CIS or Korea. IMO it's the best format, you can lose once in groups, but after that everything is serious, you lose = you out.
Edit: for selecting teams which go to Iceland Masters, NA format is more suitable. Because it really determines 1-2 best teams and it's very important to do so. Meanwhile in EU format some flukes can happen.
